That sounds like an interesting book, I will have to check it out.

I didn't mean to suggest that a single skill guild is sufficient for any single person.

I believe the answer is somewhere in the middle of where we are now, groupings like subreddits, and what you're talking about.

Something where participation takes real effort, but in a way that complements other guilds such that members can "cross-pollinate" and grow as an individual opposed to growing into a mold.
