At the ACR Winter Meeting, we discussed Blogs/RSS and tried to give some ideas about possible applications for rules. However, we didn’t have much time to provide background.
Inter Alia blogs about an RSS tutorial created by Alex Barnett. The tutorial with Mr. Barnett’s audio narrative, uses Flash to demonstrate downloading, installing, and setting up a news (RSS) aggregator (FeedDemon). Mr. Barnett even demonstrates some of the differences in ways that various feeds work. He also discusses why he uses RSS feeds.
FeedDemon is available for a free trial; after that, a small charge. Other aggregators are available. We demonstrated two a the Winter Meeting: SharpReader and MyYahoo! MyYahoo! is an online aggregator for which you sign up and then may use free of charge. SharpReader is available as a downloadable client software. It is free of charge, works with Windows XP, but requires that you have installed .Net 1.1 . The SharpReader site explains that.
Hope this helps.
