We have been using RSS feeds in WebCT for a while now and Alan Seatwo has been experimenting with them in his work with the Community Knowledge Transfer Service. We have been using Feed2JS but now there is a new kid on the block called FeedoStyle.
It allows people to pull any RSS feed into a stylised module on a web page. The idea is to allow blog and other website publishers to include new content directly onto their site in a very easy way. The service is easy to set up and does not require the creation of a user account.
The good thing about FeedoStyle is that it allows multiple feeds on a page something Alan had difficulty doing with Feed2JS.
