This is a great article on the benefits of solitude you geeks should read, from HBR.

The protection of the screen mitigates many problems of group work. This is why the Internet has yielded such wondrous collective creations. Marcel Proust called reading a “miracle of communication in the midst of solitude,” and that’s what the Internet is, too.

Decades of research show that individuals almost always perform better than groups in both quality and quantity, and group performance gets worse as group size increases. The “evidence from science suggests that business people must be insane to use brainstorming groups,” wrote the organizational psychologist Adrian Furnham.
