Based on a quick glance, SeatGeek is far less of an affront to my eyes than Kontera, but Kontera would look just like this if they used the same CSS styles. (Not literally, but you get my gist.)<p>I don't think in-text advertising is leaving us anytime soon. So, I think the best thing you can do is to make the difference between normal links and ad links very noticeable. The little pop-up should not be very large, slow to load, or look like it might be some type of legitimate information source. It should totally say in big letters at the top: "Advertising by SeatGeek." Black background, white bold text.<p>I've thought about this a couple times, trying to see if I could come up with something that the established companies haven't. I really can't wait for some clever person to figure out the perfect way to put in-text ads in content.<p>Maybe there should be no ad links at all, but a little icon to the right of the phrase, that upon mouseover will highlight the phrase and display the pop-up.<p>Ultimately though this method of advertising gives site owners the opportunity to deceive their visitors into clicking ad links. Less so than Adsense, I would think.<p>---
