New Yorker had lost its luster, but after I was interviewed and found out what a twisted joke their "fact checking" was, I lost all respect for them. I had lost respect for NYT years before after I tried several times to correct egregious errors in news stories overseas and they were anti-interested. I view all journalism today as suspect - no matter who does it. One reason for this is that most journalists today just don't make enough money, and haven't got the budget to do real research on stories.
Matt Taibbi is quite good. He tries hard, and he's smart enough and experienced enough to do quite well. With a real budget and higher salary, who knows what he might do?
