On a more serious note, I see the old "like" link is still in place and seems to work...is this going to be phased out or is the "like/dislike" buttons (and no bacon button...dang it) in a beta stage?
On an even more serious note, I can see this causing grief in the Aviation Section. With so much bickering over miniscule issues, they will likely loose the context of the thread and worry about the dislikes.
