Ask HN: PivotalTracker is free, does that make you nervous about using it?
We use Pivotal for a number of projects; every startup i meet seems to be using it. Nobody seems to talk much about contingencies as there's not really an SLA - or at least anything legally enforcable... It's not that I don't trust Pivotal Labs, but it makes me wonder if there's not a business opportunity - clone Pivotal, charge money, provide SLA, profit... thoughts?
