The Clarkbot is a Perl script written by Rick Heller. It searches the Feedster RSS search engine for references to “Wesley Clark” To be picked up by the Clarkbot, a blog must generate an RSS Feed, and that feed must be listed with Feedster.
Of course, if too many people reference the Clarkbot then it’s all going to get a bit circular.
Edit- I want a version of the Clarkbot that I can set to ‘search term of the day’. One day it’ll be looking up all the mentions of toilet roll in blogs, the next tree frogs.
