Bloglines is hands-down the best RSS reader I’ve used. This includes desktop applications on Windows, OS X, and Linux, and web-based applications. Here are the reasons why I use it to read my favorite websites.

Synchronization
Since it’s a web-application I can use it from work, home, and on friend’s or coworker’s computers. I read an entry on the T on my Sidekick and when I get home it’s marked read in my aggregator.

Interface
HTML Frames have their uses (rarely) and this is one case where they’re used to great success. I can’t deal with aggregators who display your subscriptions as one big long crazy list. I subscribe to some high-traffic feeds and I don’t want them cluttering the screen when I’m trying to see if Joel Spolsky has posted anything new.

Bandwidth-friendly
Bloglines only grabs a feed once for all of its users thereby bearing the bandwidth burden for the sites that provide syndication.

Feature-rich
Want to know how many Bloglines subscribers a feed has? Want to know what people who read your blog also subscribe to? Want recommendations based on your current subscriptions? Bloglines has all these features and more.

Support
Less than a day turnaround for a question that I really shouldn’t have asked (it was in their help documents).
