If we ran politics here, I'd be giving you the same rant about HuffPo and RCP.
But we run tech and entrepreneurship here, and if things break the wrong way for us (and him, I guess), Michael Arrington could be the next Robert Moses.
People don't see this is what we're trading real journalism for. Diva bloggers that have to be kissed up to.
I think the way to make today's tech bloggers better is to pay attention to the stories and reporting that matters. Besides voting with our clicks, there is little else we can do to influence the market.
# edit: I think this means news is largely fungible. That's why there are so many social filters like twitter and tumblr and HN. Your peers voting on content is a better way to filter than tracking a reputable source.
