Judging from the rating numbers already, for being on a channel that is hardly a ubiquitous part of everyone's cable-lineup, Olbermann is doing very well already... He's not irrelevant to his followers....and more than Glenn Beck is...to his followers. Oh, you better watch Beck while you can... He goes off the air soon...
But, of course, you can PAY him ... $50/year ... to have it on-demand...
