I guess the site's advertising income can come from anywhere???
I don't usually see the ads, but had to log out/in for a fix just now, and saw that awful "tell JM to pay attention to Oregon families" thing! I saw it a couple of days ago over at HuffPo or someplace, but wouldn't have expected it here!
... well, it's in the rotating-Google-ads space at the upper right, so you may or may not see it, and I guess from that source it's less control-able what content will show up...
