Instant RSS
Sabifoo is a tool that lets you create an rss feed (and a web page) from your instant message client. Essentially it’s a “robot” that publishes whatever you send to it on a web page/feed. Some cool additions to this service would be private feeds, multiple person chat capability (i.e. invite the sabifoo bot to a chat to record and publish an interview chat between two people), and enclosures for links to media and file transfers.
