That list of further reading below is woefully inadequate. And I can say that since I posted it originally.
The basic ideas:
--Seek hands-on folks. When trying to find someone to read to learn about innovations, seek those who are actually doing the work.
--Beware consultants. Remember they're selling something.
--Seek diversity. It's not easy to find.
--Avoid feedback loops. When you run into a couple of bloggers or sites who appear to be feeding on each other in a continuous loop of links, drop one. Seek new ideas elsewhere.
--Find those who disagree. When you run into a blogger who is saying something contrary to everyone else, keep reading and coming back for more. Unless they're just contrary.
