You need to take down the ads. Ads are good for monetizing when no other monetization method is more effective. Right now we have a few clear, valuable call-to-actions: get a bitshares account, buy bitshares, buy bitUSD, and sign up for the mailing list.
Anything else just distracts users away from these important goals, all while damaging the perceived value and credibility of you and bitshares on the whole.
