Sanger himself experienced [interminable fights over credentials] in his fight with Cunctator at the dawn of Wikipedia; Cunc questioned Sanger's authority, leading Sanger to defend it with increasing vigor. As Sanger said at the time "...in order to preserve my time and sanity, I have to act like an autocrat. In a way, I am being trained to act like an autocrat." Sanger's authority at Wikipedia required his demonstrating it, yet this very demonstration made his job harder, and ultimately untenable. This the common case; as any parent can tell you, exercise of presumptive authority creates the conditions under which it is tested. As a result, Citizendium will re-create the core failure of Nupedia, namely putting at the center of the effort a process whose maintenance takes more energy than can be mustered by a volunteer project...Link
Citizendium is based less on a system of supportable governance than on the belief that such governance will not be necessary, except in rare cases. Real experts will self-certify; rank-and-file participants will be delighted to work alongside them; when disputes arise, the expert view will prevail; and all of this will proceed under a process that is lightweight and harmonious. All of this will come to naught when the citizens rankle at the reflexive deference to editors; in reaction, they will debauch self-certification (leading to irc-style chanop wars), contest expert preogatives, rasing the cost of review to unsupportable levels (Wikitorial, round II,) take to distributed protest (q.v. Hank the Angry Drunken Dwarf), or simply opt-out (Nupedia in a nutshell.)...
The philosophical issue here is one of deference. Citizendium is intended to improve on Wikipedia by adding a mechanism for deference, but Wikipedia already has a mechanism for deference -- survival of edits. I recently re-wrote the conceptual recipe for a Menger Sponge, and my edits have survived, so far. The community has deferred not to me, but to my contribution, and that deference is both negative (not edited so far) and provisional (can always be edited.)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
