I am also wondering how to maximize income from something like this. I've been normally adding something like a popunder from
Plugrush or
Ero-Advertising, and some banner ads from
Exoclick, but that does not make a lot of money, in the end.
I am thinking about adding some advertising in actual posts, between posts, some other types / forms of advertising to the site also (I am not sure exactly what this could be yet, some kind of cameras, dating, sex shop, things like that). There is plugins for something like this also. I think that if done correctly income can be 4 or 6 times larger than with regular ads (banners + popunders).
