Why do Startups Fail?

Divergent opinions (David Feinleib @ Mohr Davidow Ventures, 37signals). Also speaks to the tension between vc's and the entrepreneurs that they invest in. I'd tend to agree more with the latter view from 37signals - particularly this point: "'It’s not just how fast you run the race that matters. It’s how fast the race is run. When it comes to startups, speed wins.' That’s just ridiculous." The comments in 37signals' post are also pretty interesting.
