Can confirm, I was there and many had been warning anons and calling for a migration for weeks.
When Q called for it, lots of anons were trying to create a new board, I think BO just happened to have his ping pong ball called and rolled with it.
It worked best that way, because as it turns out the people who will push to be a leader will always be a worthless faggot.
Chances are way better if you just close your eyes and pick an anon at random.
