Personally, I don't like the "Likes" button, no pun intended. Since this is a forum for discussion, I prefer that someone would post and say, "I like your post for the following reasons..." rather than press a button, which is too easy to do. Secondly, it gives too much clout to Stromboli, (just kiddin'), however, it does give the appearance that some people are being rewarded (yes, I'm jealous) and, more importantly, we don't know why. We should encourage open discussion/controversy, not likeability.
Just my 2¢.
