I don't think this really adds any value. In fact, highlighting characters in lists like this might make it a self-licking ice cream cone where the top people keep showing up because they're on the list. Even if that's not the case, I remember when the site had the top 10 lists for people, places, characters, etc. The lists tended to be relatively static, and the people were always the chicks with the big boobs and/or Jade Raymond. I suspect that the tastes of the GB community haven't changed much since that time.
