These ads are a really bad idea - not just more annoying than "Web Sling Dr. Octavius" and "Earn Your Degree While You Work", but they also make you look like you're promoting something when you post. I hope RP is making a lot of money off them, otherwise it's just going to tick people off with no reward.
ADDED:
Speak of the devil, here I am advertising what Google thinks a frequent flyer wants to know.
