And who exactly portrays themselves as "top posters" and who exactly gave them that title? I see us all as equal posters. I see nobody here above anyone else.
Possibly he just means in number. The people who post the most and thus the people who most recognizable and in his eyes, the top.
But whatever you DO mean, this is a severely random thread. I really don't think everyone jumped ship and went to DCUO like that. I doubt they sever all ties with an MMO and it's community just because they play another MMO. You don't have to be loyal only to one. :p
