My guess is that the reason YPN hasn't implemented adlinks is lack of sufficient ad inventory. A four-link adlink unit, as implemented by Adsense, features 4x10 = 40 ads. The targeting is often poor, usually poorer than the conventional Adsense ad units. If people here complain about YPN ad targeting, how much more so if YPN were to implement adlinks? Especially with their relative paucity of good, diverse advertisers?
