I would prefer to fork Wikipedia as well, but in practice I don't think that works, given the many failed Wikipedia forks of the past 20 years. On the internet, the only way to get any alternative to a widely-used source like Wikipedia is to use a significantly different approach. Otherwise, you just look like a cheap knockoff, even to people who might otherwise agree with your approach. Worse is better, after all - worse in most ways, but better or different in at least one innovative way.

Well, here’s hoping grokpedia goes and joins the rest of the failed attempts.
