I've been using bloglines as a web-based RSS/Blog reading client and so far, so good. I'd been using the product pluck for a while which is a thick client that essentially did the same thing, only it only worked with Internet Explorer, which I don't use anymore. Bloglines has firefox browser integration and a good interface. If people are using bad RSS XML templates (Noel), then the feeds don't come across correctly, otherwise, it works great.
