The "teams" thing first started before the last book was released. The only teams were Team Edward and Team Jacob (and Switzerland), and they referred to which person you thought Bella should pick. But even after Breaking Dawn came out and Bella made her final choice, the teams thing continued and sort of expanded to people picking the character who they liked the best (not just Edward and Jacob anymore). So it started one way, but sort of turned into something else.
