A metropolis shares one key characteristic with the Web: both environments are dense, liquid networks where information easily flows along multiple unpredictable paths. Those interconnections nurture great ideas, because most great ideas come into the world half-baked, more hunch than revelation.

A scenius is a beautiful bubble that only forms under special conditions: friendly competition and appreciation, rapid exchange of new ideas, mutual sharing of success, and most importantly, a buffer against the outside world that creates space for transgression and general weirdness.
