Was she/he well-behaved?
With this number of readers, you should really put some ads on here. You could make a little something to reward you for all the effort you put into doing this. You could start with a simple Google Adsense integration, serving relevant Google ads. But you could also sell a little box in your sidebar to a local business. Or two. A lot of bloggers with many fewer page views do it. Not to mention the newspapers.
Pet peeve about a former or theoretical someone living with you?
you're not the first to suggest it, but sadly Wordpress don't allow you to integrate with any ad thing, including Adsense! I do this just for a little hobby really anyway so its no big deal
