To me it sounds like the success of NitWiki was down to the culture of the 30-person team. I'm guessing this stemmed from some leaders in that group, and applied to more than just the wiki. I'm not sure that much has changed over time - it's just not trivial to cultivate the right kind of culture. Re: the public vs private debate, if you want to make a great public wiki, then maybe you have to make "open" the default. This requires letting go of the fear of sharing too much, although my personal experience suggests we tend to be more afraid of this than is necessary (e.g. "stealth mode" startups).
