It's a process, you rate, you shortlist, you narrow it down to a manageable number, then you decide. Some people can't make a final decision, so they ignore the contest. Out of sight out of mind sort of thing. Time passes and they never come back. Or maybe they have a few names they really like and suddenly they get an epiphany and come up with their own unique name they like best of all. Or maybe something else, we will really never know.
