It's probably not worth it for the $100 or so advertising would bring in. I'd focus on using your site to build your personal brand, use it to drive subscribers to your twitter, facebook, etc. pages. Also consider setting up a mailing list which you use to periodically send out updates on interesting things you're working on. That way onces you have something you want to promote (be it a book, website, event, etc.) you'll have a solid following to which you can promote it.
