I'm working on a guide for developers who want to blog, but don't know where to start. What questions should I answer?

The title says it all. I'm working on a brief guide tentatively titled "Start a technical blog today." I want it to be as useful as possible. If you've ever started blogging, or wanted to start but couldn't, what got in your way?

UPDATE

This course is now live!
