To be honest, most of the GC-named characters are only mentioned in passing. The exceptions being the ones named after sn23, Dan and Beale. Everyone who's commented on this thread so far as been referenced - apart from ST. His name is on the front cover, though.
Waitaminit A character that is a cross between me and ER is a cabinet minister? Cabinet ministers are old drunken sad lonely bastards with no redeeming qualities whatsoever... oh, I see. Carry on.
Most of the characters bear no resemblance to the GC user in question. For example, Tina is a lesbian, when we all know the real Tina loves the schlong.
