I agree with only parts of Larry's post.

This is not really true. Linus Torvald's was an unknown nobody when he started. Current major projects like KDE and Gnome are led by young upstarts. Most of the leading lights in free software are leading lights because of talent and willingness to work -- most are _not_ "world-class computer scientists".
The "world-class computer scientists" work at Microsoft -- and turn out a mixed-quality product. Or they work in Universities, doing valuable and original research. But they don't devote a lot of time to writing and releasing free software -- and nobody misses them.
I think this is very important to understand: credentialism is a killer for volunteer projects. A hostility to credentials is possibly worse, but we are in no danger of that. But a hostility to enthusiastic amateurs (in the postive traditional sense of that term) is death to a volunteer project. If that keeps the credentialed away, then so be it.
Would it be nice if real experts came to a free encyclopedia project in droves? Yes, of course. It is likely? No more likely than it is in the case of Linux and the free software movement, which is to say: not likely at all.
The wikipedia model *is* significantly different from the model of most free software projects, for a lot of the reasons that Larry mentions. And it is possible that a less "open" model will be useful soon, using Wikipedia articles as a base.
