hmmm
although I agree that Facebook and Newgrounds are really different, I don't think the like buttons make much of a difference.
In fact, I can't think of anything terrible enough to ruin Newgrounds (except removal the audio portal, the flash portal, the frontpage list of featured submissions, the review feature, and the forums. Basically, a COMPLETE transformation into Facebook)
regarding the submission, I think it's been animated pretty decently
