People already know that gamer culture exists (The King Of Kong would be another example), but Robert profiles it rather than making an argument for it. I think it makes for a better, more inviting show, but it certainly won't change minds about the quality of the object of attention.
I like comic strips and comics generally, but find the most commercial stuff worldwide (which would include superhero comics) irritating more than intriguing. I listen to Quiet Panelologists At Work and Funnybook Babylon all the time, though, because they're inviting, funny, intelligent shows. My disposition toward superhero comics hasn't changed.
