Agree. For me anything that says, "LIKE X on Facebook." is an instant non-starter. At least give people an alternative, non-social registration mechanism.
In fact, if there is an old-fashioned non-social way to do it, I'm more inclined to actually use facebook or twitter since it doesn't seem so pushy.
