Tonight, BoingBoing added in a new feature that allows you to to find "Other blogs commenting on this post" for each post. It is an ingenious use of the Technorati search functionality embedded inside of the Movable Type template that BoingBoing uses. This is a great way for a site to provide a distributed commenting system that incorporates transparency and accountability - to comment on BoingBoing, you just post something that links to BoingBoing, and you'll show up in the "Other blogs commenting on this post" page. It also discourages spammers and trolls, because all comments must be posted on the commenter's blog, and those posts are accountable - even if you want to remain anonymous, the commenting blog can now itself be commented upon, ad infinitum.

Here's how you can add it to your own Movable Type weblog template:

1) Edit your blog
2) Click on "Templates"
3) Click on "Main Index"
4) Somewhere imbetween the <$MTEntries$> and the <$/MTEntries> tags, add this to your template:

<a href="http://www.technorati.com/cosmos/search.html?rank=&sub=mtcosmos&url=<$MTEntryPermalink$>" title="Technorati Cosmos">Other blogs commenting on this post</a>

5) Click on "Save"
6) Click on "Rebuild Site"

I just added it to this blog. Here's a link to the template for Sifry's Alerts main index page. Give it a go, and let me know how it works for you!
