Revolution displays the number of likes given and received along with the post count, join date ,etc, as well as showing a list of people who liked a post at the bottom of it. Neither of those appear on Wintersday. The liked list appears as white text with a shadow on a white background though. The thumbs up icon is misaligned for me too.
EDIT: Forgot to mention, if we're going to have a likes system installed, isn't reputation kinda redundant? It's never really been clear what it's meant to be for anyway.
EDIT 2: Also, I'd personally prefer for the total number of likes somebody has given and received to not be listed on every post. Listing the people who liked a post on that post (as it happens now) would be all I'd like to see.
