There's a lot of content my friends have shared on Facebook that's pretty awesome. For instance, in the last few days I've seen photos from a friend's wedding, an article about U.S. President Obama's ongoing transition and status updates from a friend traveling in India.

We've just introduced an easy way to tell friends that you like what they're sharing on Facebook with one easy click. Wherever you can add a comment on your friends' content, you'll also have the option to click "Like" to tell your friends exactly that: "I like this."

Recently, I had a friend write a note about running her first marathon and another friend upload pictures of his new baby. In both cases, they ended up with over 30 comments, all saying: "Awesome!" "Congrats!" The aggregation of the sentiment "I like this" makes room in the comments section for longer accolades.

This is similar to how you might rate a restaurant on a reviews site. If you go to the restaurant and have a great time, you may want to rate it 5 stars. But if you had a particularly delicious dish there and want to rave about it, you can write a review detailing what you liked about the restaurant. We think of the new "Like" feature to be the stars, and the comments to be the review.
