This blog, StrongTowns.org, consistently has some of the highest-quality, focused content that I've seen in a long time. I'd encourage donating if you also got something out of it.
Yea this site is fantastic. I just discovered the site because of two threads that made it to the front of HN today. I've already spent a couple hours reading all the other articles, I think I'll likely become a member
There is also a great interview about it on the amazing econtalk.
