it might be nice to be able to like a friends photo i feeel obligated to comment but may not have something potent to say so a like button of some kind on friends pics might be handy.
I think that it's not such a bad idea to have it on ones profile(for pictures, playlist, videogallery, friendscomments).
Since Lush loves to be customizable for every person's enjoyment I think that having like button on/off option would be rather neat.
