Google Reader

Google Reader makes it easier to keep up with your ever-expanding reading list of content from across the Web. Spend your time reading what you care about most. Reader automatically gets the latest news and updates for your favorite sites. You can sort your reading list by relevance, which will guess what's most relevant to you based on how you use Google Reader (such as which items you decide to actually read).
