And it's that Sanger really isn't the expert on Wikipedia (or on community-building in general) that he claims to be. Sure, he was involved with Wikipedia in its early days -- but that was 20 years ago. That experience is largely irrelevant in commenting on Wikipedia as it exists today, because the organization has evolved significantly over that time, and he hasn't been involved in that process.
