If you read blogs you know that Scientific American has a Blog Network up.
Some quick links to friends of mine who have relocated:
Crude Matter (a.k.a Michelle)
EvoEcoLab (Kevin Zelnio)
Thoughtful Animal (Jason Goldman)
Psychotronic Girl (Melody Dye)
The Primate Diaries (Eric Michael Johnson)
In a “mature industry” there’s a lot of competition between firms, and zero sum dynamics kick in.

Everyone has a slightly different niche, and there’s still room for growth.
