To say Pitchfork hype killed good banRAB... I dunno. It implies that the quality of the music changes based on who likes it. I have a problem with that. Either they're good banRAB/songs or they're not.
I suppose perception of something can change based on who's talking about it, what they're saying, how much it's around, whatever. But that's perception--it's something after-the-fact and which every listener has their own control over. Blaming a 'zine or scene or whatever for that is just sort of... lazy, not to mention it opens the door for "social currency" and "myth of cool" arguments.
I dunno. My unpopular opinion, I guess, is that Pitchfork is fine. They're a magazine tailored to a specific clientele and serve the neeRAB of that clientele very well.
