Chirrup is a bit different -- looks like more of a programmable API than something for end users. Chirrup fetches all of the replies from Twitter, and sorts them by URL so you can have a comment feed for each page in your site. This is actually not very much our new feature at all, since Chirrup is a feed service (pull from Twitter by API) whereas ours is a way to post comments to Twitter at user's choice (push to Twitter by user) However, it is quite a bit like Backtype.com's new Backtype Connect, which tracks not just Twitter but comments from other all other kinds of blogs (Wordpress, Typepad, Six Apart), Reddit, Digg, Hacker News. And even Posterous. =) Here's Backtype's recent blog post just the other day about Backtype Connect API, which is fully programmable. http://blog.backtype.com/2009/04/api-backtype-connect/ http://blog.backtype.com/2009/04/api-backtype-connect/ They also have an awesome Wordpress plugin too!
