There’s a small feature on the way that’s about to make another big change to the way people use Facebook: the ability to “Like” comments.
Much like you can currently “Like” status updates, wall posts and other items in the News Feed, Facebook has started rolling out a “Like” button for comments. The feature is not yet live for everyone.
The functionality is much the same as traditional “Likes.” In a blog post, Facebook writes that, “when you click ‘Like’ on a comment the commenter will receive a notification. Other people who can see the comment based on its privacy setting also will be able to see who has liked the comment.”
Already the web’s number one time sink, expect this feature to add a few more minutes per day to our collective use of Facebook.
