If you're saying programmer I'm assuming there is already this level of experience, but I went ahead and made my own blog set up. This was mostly really to learn Rails. Even though I am mostly doing strictly Ruby stuff at the moment, I hear of or see features I want to add to the blog so little by little I pick up more rails techniques.

For just having something already set to focus on your writing, I really like what I've seen from Jekyll, I don't have a need yet but I'm definitely keeping it in mind for future projects.
