I've been posting more on LinkedIn these days. Short little nuggets about TDD that people really seem to respond to. It's all out there if you want to read it, just look for my name on LinkedIn.
Anyway, I did so many of these that I realized I could make a sort of lightweight handbook out of them, for the the practitioner why just wants to sharpen his or her TDD skills. So I did that...
It's called "The TDD Companion". It's a really cheap little book ($8, even cheaper on Kindle), each page is one of those nuggets, and the organization is very loose. I thought some people who follow this blog would be interested.
