i think the likes are still there because facebook has them. they used to be used in the search, but it was abused when people found out it did something real. i don't think it helps as much now. i also don't think liking your own helps anyone. so they can like it if they want but, i don't think it helps any. i suppose for curious buyers they might take a look there, but i think your own name is under it, so it looks just sad to have only your stuff there.
