An update on the blogosphere's reactions (and resources) to the London Bombings (7/7/05 16:30PST)

All of my thoughts and prayers are with the victims and survivors of today's events. The blogosphere reaction with an outpouring of emotion has been tremendous. I wanted to share some information and statistics taken from what Technorati has observing throughout the blogosphere today. We have put up a special page on its site to cover the events in London. The URL is and will continue to be updated with information and live content as it happens.

There were just over 500,000 posts since from Midnight - 11AM Pacific (bombings took place at 12:51AM Pacific. This represents a 29.8% increase from yesterday's 840,000 posts (385,000 from midnight-11 am yesterday).

Here's a set of first hand accounts from the blogosphere:
"Fate is a strange thing. On this particular day a series of events transpired such that I ended up on a Tube train that was destroyed by terrorists. Fortunately it was only the carriage in front of me, but tragically it resulted in a serious amount of injuries. This is my story."
London pride meme starts as people post odes to their city.

AOL and Technorati team up for Live 8 coverage

Woo hoo, AOL Music, the exclusive online partner of Live 8 and Technorati have teamed up to give dynamic information on what bloggers are saying about Live 8, and this info is syndicated on their Live 8 homepage (check out the bottom of the page, called "Live 8 BlogZone") More later...

Become one of 50 bloggers going backstage to the Live 8 Concerts

The gracious folks from have procured 10 backstage press passes to each of 5 of the following Live 8 concerts - , , , , and . The folks at and Live 8 believe that bloggers can help to shape the media and bring a new voice and perspective - and help to set the agenda - before the G8 conference in Scotland. (BTW, check out their new blog.

In addition, Richard Branson of Virgin Airlines has donated his airplane to fly the Live 8 crew from New York to Edinburgh and back, and up to five bloggers will be given the opportunity to fly to Edinburgh and back with the Live 8 group. The idea is to blog the trip, including the beginning of the G8 summit. The flight departs from JFK in New York at 7 p.m. on July 3; the same airplane will bring the bloggers and whoever else back to New York on July 7. Lodging in or near Edinburgh will also be provided.

So, here's what's up: This is a call to bloggers to give all of you the opportunity to get one of these backstage passes, and possibly on the flight to Edinburgh. Think of all the cool stuff you can do - set up a podcast and interview the bands, make a great photoblog, videoblog it, heck maybe you can end up playing air guitar in front of millions, who knows?

Seriously, the goal of this is also to get millions of bloggers posting about Live 8 - the fact is that there are 30,000 children dying in Africa every day - no one is reporting on it, and we aren't doing anything about it. So one of the goals is to help set the agenda of the mainstream media, and this represents a moment of pregnant possibility - for bloggers to create proactive change, not just reactive change based on other news events. It is our opportunity to help to shape the news conversation for the good of us all. And for our leaders to hear the voices of millions when they sit down at the G8 meeting.

So, here's what you need to do:

  1. Go to and watch the video and sign the declaration. Get up to speed on what Live8 is all about.
  2. Go to and put one of the badges on your blog. It is pretty easy to do, you just need to add the code on the badge page to your weblog template.
  3. Go and read the posts about Live8 on Joe Trippi's blog and on Powerline - this is a nonpartisan effort.
  4. Pick the show that's nearest to you - and send an email to me, Joe, and to John with the following information:
    1. Your name and age
    2. Your blog name and URL
    3. Which show you want to go to (please only pick one show), and
    4. Your snail mail address (so we know where to send the show packets)
  5. Go and blog about Live 8, and tag your posts with the Live 8 tag (instructions on how to do this are here). You've got to put the badge up on your blog and have posted at least once about Live 8 with the tag to get selected.
  6. Keep an eye on your mailbox. Given the incredible time crunch, we'll let you know what's up no later than Thursday June 30th.
  7. Tell all your friends. The goal here is to get 100,000 blog posts out before the G8 summit, and to get as many people out there blogging about Live 8, third world debt relief, the plight of the hungry and poor everywhere and what we can do about it.

There may be additional credentials that we can get from the Live 8 people, and Joe, John, and I are going to work our butts off to get credentials for the other shows as well, including Toronto and the shows in Great Britain. More to come. In the meantime, please go out and listen, read, and blog - together perhaps we can help to shift the conversation, and influence country policies to help to make poverty history.

Live 8 Blog Central launches!

I'm proud to announce the launch of Blog Central for the Live 8 concerts, at We were asked by the Live 8 folks along with Joe Trippi and John Hinderaker of Powerline to help achieve the vision of Live 8: "We don't want your money, we want your voice".

Come and add your voice - there has been no better opportunity for bloggers to be heard. The Live8 folks have a bunch of really interesting and exciting things planned around the concerts and also around promoting the conversations about African debt relief, ending world hunger, and getting the leaders of the G8 countries to put this high on their agendas for the upcoming G8 summit in Scotland on July 8th. We've got widgets that you can add to your blog to signal your support, and to be counted, all you have to do is tag your posts with the "" tag. It's simple, and fun! To add it to your posts, add this code:

<a href="" rel="tag">live8</a>

And to add the widgets, there's a page with a selection to add to your template.

AO / Technorati Open Media 100

I'm happy to announce that the AO/Technorati Open Media 100 list has been published! This list includes bloggers and influencers who's groundbreaking work is changing the technology industry, journalism, and marketing. This list is a start, and I know there will be much discussion and I personally invite your comments.

The process for compiling the list was relatively straightforward. Tony Perkins and his editorial team were responsible for the subjective work. Technorati's role was to provide the objective methods via our Technorati Top 100 Blogs list. We also included all of you by asking for nominations.

We hope this list provides a framework, starts some discussion, and, ultimately, brings some new readers and attention to the blogosphere. This was a first and we'll continue to refine and improve the process over the next year for 2006 Open Media List. We hope you'll continue to be part of that process as well.

On Search Engine results comparisons: Where's the remaining 99.8% of the results?

Recently, Tristan Louis wrote two very interesting posts on comparisons between Google, Yahoo, and Technorati's results on searching blogs and counting references to the Technorati Top 100 bloggers as well as the long tail of 11.5 Million bloggers out there. If you haven't read the posts, please go over and have a look at both of them - there's lots of very interesting data and analysis in there, and I think there are some very interesting conclusions that Tristan draws from the data.

However, I believe that Tristan's analysis begs a question that hasn't been asked yet: How accurate are the numbers that search engines report about the size of their result sets?

We give a lot of faith to the numbers that search engines report, when trying to guess how popular something is. Google reports today that there are "about 624,000" results for "long tail". Yahoo reports "about 779,000" results. People quote these numbers as accurate statistics, and Tristan is using these numbers to do some comparative analysis of the coverage of Google, Yahoo, and Technorati's indexes. However, I'm having difficulty ascertaining the accuracy of these numbers. I've listed some examples below, and a simple how-to so that you can check yourself for your favorite searches.

My questions with Tristan's conclusions are not with his analytics, but with the underlying data that he starts with.

For example, when you search for all the results for "Tristan Louis" on Google, it reports "about 575,000". However you can only navigate through 703 results of the entire set. Perhaps this limit exists to more easily keep their indexes small and in RAM (which means they can stuff more indexes onto a single machine). Perhaps from a user (and business) perspective, their testing shows that almost no one except for researchers will go past the first 5 pages of results.

But if you can only view 703 results of about 575,000, where are the other 573,297 results? That's only 0.2% of the search results that the estimate claims. Where's the missing 99.8% of the search results?

Yahoo search says that there are 890,000 results for Tristan Louis.

However, I can only see 1000 results. That's also only 0.2% of the results that the estimate claims, the same viewable results to estimated results ratio as Google. Where are the other 889,000 results?

I don't know whether Tristan's analyses are correct, or if they are simply reflecting the low viewable vs. estimated results ratios of Google and Yahoo's search results. I would love to hear more from Yahoo and Google explaining the methodology behind their estimated results, and how can users access the full result sets for completeness, and frankly, for objective verification.

To be fair, these same questions must be asked of Technorati's results.

Searching Technorati for "Tristan Louis" currently shows 566 posts. Now, that's a lot less than Google or Yahoo estimated results, but not far from their viewable results. Technorati's results are by default sorted by time, and thus when you traverse the result set to the 560-566th result, you see the 566th result, which is the first result in the timeline (250 days ago, as of the time of this post) that Technorati indexed that matched the search term. Thus 100% of the reported results count (at least with this example) are viewable, thus providing a viewable to reported results ratio of 1.

Here are the steps in the experiment, that you can try for yourself, and thus repeat/verify the results we found above, and see what viewable to reported ratios you come up with using each search engine:

For Google:

  1. Go to Google's advanced search page.
  2. Use the pulldown on the right hand side to ask google to return 100 results per page instead of the usual 10 results per page. Note that this doesn't affect the end results, but it will mean you'll have to do 1/10th the clicking to find the last result.
  3. Type in your search term and click on "Google Search"
  4. Look at the result page. Look for the top right hand side of the page, where Google reports "Results 1-100 of about XXX for YOURSEARCHTERM". Note the estimated set of results.
  5. Go to the bottom of the page. You'll see the Gooooooooogle graphic, with a set of result pages (usually 1-10)
  6. Click on the last result page (usually it will be the 10th page)
  7. Check the actual number of results that Google gives you. Note that you can't go any further.
  8. Rinse, lather, repeat for your favorite searches.

For Yahoo, here's the steps:

  1. Go to Yahoo's advanced search page
  2. Go to the bottom of the page and use the pulldown on the right hand side to ask Yahoo to return 100 results per page instead of the usual 10 results per page.
  3. Go back up to the top of the page, and put in your favorite search terms. Click on the "Yahoo! Search" button on the top right.
  4. Look at the result page. Look for the top right hand side of the page, where Yahoo reports "Results 1-100 of about XXX for YOURSEARCHTERM". Note the estimated set of results.
  5. Go to the bottom of the page. You'll see the Results Page: area, with a set of result pages (usually 1-10)
  6. Click on the last result page (usually it will be the 10th page)
  7. Note the actual number of results that Yahoo gives you. I usually find that Yahoo gives 1000 results, usually more than Google. Note that you can't go any further.
  8. Rinse, lather, repeat for your favorite searches.

For Technorati, here's the steps:

  1. Go to Technorati's home page
  2. Put in your favorite search terms. Click on the "Search" button.
  3. Look at the result page. Look right under the search box on the top of the page, where Technorati reports "XXX posts about YOURSEARCHTERM". Note the result set size. Subtract 10 from this number - you're going to need this in order to get to the last page of results. For the sake of this tutorial let's call this number YYY (YYY = XXX - 10)
  4. Go to the URL bar in your browser. It should say something like:"
  5. Add the following to the end of the URL: ?start=YYY where YYY is the number of posts that Technorati returned two steps back. Our example URL from the last step should now look like: ""
  6. Note the actual number of results that Technorati gives you. Feel free to click through the results pages prior as well to verify that all the results are there.
  7. Rinse, lather, repeat for your favorite searches.

I hope that this initiates some discussion about these issues. I'm frankly interested in making sure that researchers like Tristan are accurately comparing apples to apples, and I'm all for additional transparency and verifiability in the results that all search engines provide. Am I missing something here? Can someone from Google or Yahoo help me to understand why their reported results are sometimes 1000 times larger than their viewable results? I look forward to being educated.

New Technorati UI redesign is now live on

We hit a major milestone today when we moved our new Technorati redesign out of public beta and made it live on There's even a new Technroati corporate blog to boot, and you can read all about the features of the new redesign.

This has been primarily a User interface refresh and facelift, but there's also a bunch of backend lifting we've been doing, especially the new code to separate sidebar links from post links when checking out who is linking to your blog, like this. It isn't perfect yet (we still miss some blogrolls and count them as posts) but I hope that it makes things much easier for your power bloggers out there who have been trying to sift through the duplicates and blogroll links in your results. We're also still working on ironing out some link count issues, and we're constantly working on improving performance and scalability. I can't wait to hear all of your feedback, and get down in the trenches to keep making things better.

Onward and upward! Congratulations to the whole Technorati team for making this happen. You guys totally rocked. I'm humbled to be able to share an office with all of you.

Finally upgraded the blog...

Pardon the dust, I finally got a few hours of free time, and in the tradition of the cobbler and his children's shoes, I updated the blog to MT 3.17 along with some other features, like the Technorati searchlet and Adam Kalsey's Technorati plugin and Ado's Technorati plugin for per-post cosmos numbers.

I was hoping that this wouldn't break anything, but already I see problems with Safari users. Any help is always appreciated, unfortunately I don't have the time like I used to to tweak things to get it just right. Hopefully some of the folks at the office will do a "Technorati eye for the geeky guy" for me and give me a few dope slaps. Feel free to do it anyway Wednesday night at House of Shields...
