while I do check w/ Pitchfork fairly often - I read very few reviews there. It's more a place I look as a reminder "oh, that album's out! Right." TBH, I feel like the old guy at the party more often than not. I don't even know who like 60% of the artists they talk about are.
At any rate, to echo Sev's post - yeah, they're kind of a joke journalistically as far as changing scores and deleting reviews goes to suit their current coolness. It's really lame. And honestly, that NYCG&F review sort of defined Pfork's shortcomings to me ages ago.
