Here is what ZH is good for: they have stuff before anyone else, because they'll print almost anything. For instance, after San Bernardino those guys had details way before other outlets, because they're willing to go to press with just "some guy overheard this on the police scanner and tweeted it".
So when you read ZH you see stuff first, but you place a big mental asterisk by it until their scoop trickles up the media food chain and starts to get confirmed as real reporters do actual work on it.
I like seeing stuff first, before everyone else gets it, hence my continued regular reading of ZH (again, I keep a 40lb bag of Morton Salt by my desk with the ZH logo on it, though).
