RSS

As you may or may not have already noticed, it's now possible to 'like' your Google Reader RSS feed items by clicking the "Like" button at the bottom of the post or pressing the "L" key. Google has followed in the footsteps of Facebook in order to get more user interaction. The new social features also include the ability to search for people who are sharing RSS entries with certain keywords. This allows users with similar interests to connect without personally knowing each other.
