It's not so much that there is or isn't a better source of news about startups. It's that the stories from TechCrunch that make it over here and get voted up have a high probability of being linkbait ("X Will Kill Y!") or about some Arrington-induced/centric drama. That they're allowed to persist here goes against the Broken Windows strategy of preventing social decay.

Is banning TC necessarily the best solution? Maybe not, but we don't have another solution available that's doing the job. There might also be some throwing the baby out with the bathwater here, which seriously depends on how much TC is a source of news (for HN, specifically) that can't be had anywhere else. I'm not inclined to say that they are a significant source of such news for HN.
