As a stackoverflow user, ads like this one:
...confuse the hell out of me. I just spent 30 seconds trying to find the rest of the answers for the question I was reading before I realized this was an ad, and the question didn't actually have 27 answers. I am totally on board with inline advertising, but this ad is objectively making the site harder to use.
Are there any sort of guidelines for what kinds of ads are allowed? I would like to think stackoverflow could prevent ones like this. If they are allowed or encouraged, I would implore stackoverflow to change it.
I just took the screenshot above at 7am on 2/10, so even with all the discussion and promises made in the answers below, the ad continues to run.
