immedi.at just went in to beta with their online service that allows you to subscribe to RSS feeds and receive pings to the Instant Messanger of your choice.
While most content might not be important enough to warrant subscribing to an RSS-to-SMS tool, getting to IM just might be more relevant, especially when you don't have the time to regularly check your RSS reader, but want to be notified when something of top importance happens.
immedi.at works with all major IM carriers including MSN Messenger, Yahoo Messenger, Google Talk, Jabber, and AIM/ICQ.
Use immedi.at to be notified instantly when:
* news on a certain topic is posted
* your competitor does something of interest
* something interesting happens with a favorite sports team
* your name or company is written about
* you receive new email
