Techcrunch is indeed pretty nasty sometimes, and I have criticised them here before, but it would be utterly ridiculous if hacker news, a news site for startups, banned one of the preeminent startup blogs.

Techcrunch is influential and as such it is relevant for many people here. You can ban a site that is nasty and irrelevant, but you cannot ban a very relevant site just because some articles are odious.

Banning should not be about morals, but rather about usefulness.
