art krush is strictly about art. it's like getting artforum sent right into your inbox twice a month.
vice magazine is one that everybody loves to hate, but it's updated everyday and it's writing 90% worthwhile {just don't read the user comments}.
the believer is from the mcsweeny's conglomerate, but it's never updated enough and teases you with half-articles, but they usually have interesting"online exclusives".
