I suddenly realized something. About two and a half years ago I made a change to the way robots can index my site [1] and as a result, the main page (the one you get to when you go to http://boston.conman.org/ [2]) should not be indexed at all (but links followed).
This probably had an effect on the ads Google AdSense served up [3] for that page (or any other page that had more than one entry on it).
Hmm.
It's a quick change so that the main page is indexed, but I wonder if this will have any effect to the effectiveness of Google AdSense [4].
I'm guessing … no.
But I might as well try it anyway.
