Goth has been around for a long time and accumulated viewers from a year of streaming Borderlands 2 then switching to Destiny on release. He's entertaining, interacts with the chat, doesn't act like he's better than anyone else (which most top PvPers do) and is just a generally positive person. Broman got a little popularity then just rode Goth's coattails to a large viewer count. Goth used to stream every day starting around 9am in Florida, and when Goth's stream was ending Broman's would start so viewers would move from Goth's stream to Bromans. That was when Broman's numbers were the strongest. Goth's kind of all over the place now in his streaming and Broman's numbers have slipped for that reason and also the fact that he's completely changed personality wise over the last year or so. When I first watched him he was a very happy, upbeat, positive streamer and now he regularly preaches at his viewers and berates chat.
