I'm perfectly fine with hearing about the one or two things a year that Valleywag does right from other sources than having to put up with the constant crap from them.
This coming from a guy who has every single submission, or at least his last sixty, originating from alleyinsider, the enterprise version of Valleywag.
As far as I know, this is the only counterexample that has come up in the months since the ban. I think that not being able to submit this one Valleywag story is a small price to pay to have kept dozens of crappy stories off the front page.
They brought up the Google buying Digg story repeatedly for months before Techcrunch confirmed it. I love valleywag, because they're a tabloid. They dig for dirt, throw up crap, but they break stories early and often.
Everything on Techcrunch is carefully polished press releases fed through the established PR pipeline. Everything on valleywag is actual (though often scurrilous) journalism.
