I'm not sure if this blog post is particulary insightful. Doesn't everything work like that, not only "expert communities"? Like: - Entertainment - more people watching, it means incentive to appeal to a wider audience, it often means it has to be more simple, but this is a contrast to what passionates expect, - User interface - more people using an app means UI needs to be streamlined and be less complicated (can't use keyboard anymore, we need to use touch UI now), but this is a contrast to what power users expect, - "Expert" communities - more people in a forum, this means less complicated subjects, so "experts" can't grow, they are only expected to give all the time. Maybe I didn't understand the blog post, but I see it as "the water is wet" content.
