I have a couple of hundred RSS feeds that I subscribe too. Are there any readers or solutions that let me train what articles I do and don't like, kind of like a Bayesian spam filter?
For example I'm interested in about 1% of postings on Engadget so I don't really want to create my own rules manually.
http://www.feedzero.com/ looked promising but it seems to be down a lot. http://www.bayesnews.xpg.com.br/ doesn't seem to work.
Update: This doesn't have to be a web app solution. For example I tried Thunderbird's RSS feature, but the spam filter in Thunderbird doesn't seem to filter the RSS feeds.
