Yep, the site sponsors ads were "coded" by me and because I prefer stuff to open in a new tab they do. Those other ads are via Google and the say:
Opening the ads in a new window
Generally, it is our policy to not allow Google ads to open in a new window. However, in a few markets, including China, we've found that opening ads in a new window better aligns with expected internet behavior and provides a more consistent, intuitive user experience.
Keeping in mind the importance of the user experience, we've enabled Google ads to open in new windows in locations where this is expected browsing behavior. This functionality is determined by the IP of the user, and is not an option you can select your AdSense account.
So, when you are in China CoffeeSnobs should work fine! Let me know
Small share of revenue? Correct, very small considering what they charge the advertisers and how much exposure they get on a busy site like this. We did it as a trial about a year ago and while they do provide some extra money into FairCrack (Google deposits directly into the FairCrack account) it's hardly worthwhile and I'm considering dumping them for BeanBay ads which also help fund FairCrack or selling off space direct to advertisers.
Nothing will change for a while so feel free to keep clicking on interesting ones till then.
... but the ads are on my radar for review.
