I too subscribed to the archnewsnow.com email newsletter then pretty much began to ignore it when it hits my email inbox.
Magazine wise: I subscribe to ARTnews, while occasionally read Art In America, (Just started to follow them via twitter but that's kind of moot considering I rarely actually sign into my account), and occasionally Art Forum.
I also read the art sections in Time Out NY and New York Magazine. They have some fairly reliable sense of whats going on exhibition wise and to borrow the phrase you just used, I take every art review I read with "a grain of salt." Sometimes, I drop by the NYTimes site to see if they have an indepth interview or exhibit review.
I also subscribe to several cultural podcasts which only one is specifically aimed at art, that being the MET Museum podcast and that's not too regular in terms of its publishing podcasts in a timely and consistent fashion. The rest are NPR interview shows that once in a blue moon will interview an author who wrote a book on art criticism or theory, and even rarer an interview of the actual artists.
