Hope for the best. It's all just random. People tell you they're nominated and everything but I've been asking question all day and I get on average 3-4 votes per answer (maybe not on this one, Idk) and I still haven't gotten in there. But then, there were these random users that no one even knows that are in the hall of fame. Just hope for the best.
