they really do produce a lot of great content, without some kind of narrow focus i'm not quite sure what i should recommend.
i particularly love their weekly "Sunday Reading" feature even though it's not exactly original content. my favorite TNI blog is probably Socialism and/or Barbarism by Evan Calder Williams, though he often spends a lot of time talking about obscure Italian films that I'm not really interested in.
the article that got me into TNI is not actually even from TNI, it's from ECW's old independent SaoB blog before he signed on: An Open Letter to Those who Condemn Looting. i initially discovered TNI when he stopped posting independently and linked to his new place.
