I think it seems to be a very efficient organization for a group of smart people putting up some money and make investment decisions together.

Though it's not described how they're all collectively structured/related.
Also super interesting to hire a psychologist! Founder breakups and founder dynamics are one of the hardest things about early stage startups (as YC has said before), so this seems an important step in trying to prevent those, and lead to overall more successful companies and investments! I wonder how long before every investment from will have require cofounders to go to couples counseling like the Genius folks do.
First Round Review is a good example: http://firstround.com/review/
Or, go to a16z's homepage: it's all home-grown content! The company hired Sonal Chokshi from Wired to actually be an editor -- not a PR person.
Probably doesn't hurt to have a huge network of important contacts though :), the need arrives at unexpected times.
From there, I started helping out with events and tech/ops at YC and joined the team to help out internally, officially (Tara and co have been doing so much already)! All I've got to say is I came for the experience, and stayed for the community.
I was at a medically-oriented place where there were a few pure EE engineers, and there was a lot of frustration by higher-ups for the EE's being clueless about medical things. The biomedical engineers were okay.
Chief of Staff in my particular case was mainly everything an Executive Assistant does (administrative work, research, gatekeeper, etc) plus anything else that came up that I could help out with.
sans the sketchiness, of course. :P
