If I had to guess, sites targeted at the early-adopter-techy crowd probably do far better after being reported on TechCrunch than things targeted at say recent parents (or your niche market of choice).

In any case, yes, threats and violence are not cool in any way. I was just commenting on the effect that TechCrunch has on the community as a whole, which I don't think is all that huge. Its more a place to read about startup news, and can be solved by simply subscribing to something else in your RSS reader of choice.
