The TL;DR is "input == output". The key is to not spend time thinking about what to write, but instead constantly be doing things and writing about the process. When you have a lot of input, you can produce a lot of output. Trying to "invent" a blog post is a pretty bad idea. It needs to be based on a real experience. I'm not at the Coding Horror level but I do post about once a week and have been blogging for ~2 years. Check my profile for a link to my site.
