For a while, before I was in-the-know, I tried different RSS aggregators under Windows and OSX, including Outlook 2007, Vienna and netNewsWire. They're pretty nice, but then I found Google Reader. Like everything else Google these days, it's a Web 2.0 application and since most of the time you're online when you're wanting to look through your plethora of RSS feeds, it's very convenient. No more worrying about synchronization and cross-platform feed settings. You can even import and export OPML files to and from Google Reader in case you still want to synchronize your Reader and non-reader feeds.

So, as per typical google style, you can easily search through all of your feeds, it supports keyboard shortcuts for quick and dirty navigation, and even trends what you read.

It constantly recommends other feeds that you might find interesting too, and my feed list has been growing because of it.

One of the really cool features is integration with Google Gears, which allows you to even use reader in "offline" mode. You can click the "offline" mode button in reader, and it will download the most recent 2000 feed items for your viewing pleasure in a disconnected state.
