Well it's quite a good week to be focusing on one of my favorite subjects – promoting professional geekery, the idea that people can (and in many cases) should turn what they love into a career. It's "Speak Out With Your Geek Out" and let me focus on #4: Starting The Damn Blog.
Why not just Starting The Blog? Because you (and others) have thought about a blog so often that it's not just "the blog I want to start" it's "the damn blog I should get to."
So, start it.
