I also have a personal site, and when Wordpress started shoving ads into their free blogs, I started paying a few bucks to host it ad-free. I recently published a book, and people can buy that if they want to thank me, or just keep reading my blog if they don't or can't. I will not sell out my readers (or "monetize my brand," or whatever you're supposed to call it), because I believe in the web as it used to be.
