Some of you have commented on some odd advertisements that have been appearing on the website.
Just think of it as our version of Adbot. It latches onto certain things being discussed at the time, and finds something, and pops it up there. It'll sometimes come up with things that support our views, and sometimes things that oppose our views, like the add to help defeat Bachmann.
There is no real control over it. Pay attention to, or ignore it, at your own discretion.
