I came across a very nice page on RSS Readers. This looks like a very complete listing of RSS Readers, including client-side applications for various operating systems as well as web-based aggregators.

Before I got into blogging (writing but even more importantly reading blogs), I never quite understood the big deal about RSS. Sure, there were some decent news sites out there (both commercial and fee-based as well as free) that offered RSS feeds, but it appeared to be over-hyped. But the killer application for RSS is really the blog, as there’s no way I would be able to keep up with the blogs that I’m reading without using an RSS aggregator such as Bloglines. Back in the Nineties, I used to read a lot of usenet newsgroups. In many ways, RSS feeds for blogs have replaced newsgroups for most of my purposes.
