If you don't have Facebook or Twitter and you'd like to participate, you could always register a Twitter or Facebook account for the duration of the contest. Once it's over and the winner is chosen (you'll want to wait until then so your entries aren't deleted), you could close your Twitter/Facebook account after that.
