i think it's just oversaturated....the banners were on every tube for so long. i ran skins for it rotated with
http://www.mofosnetwork.com. in my opinion the iknowthatgirl skin was far better design wise (even though the same designer did them both) but the mofo's network skin got 3x the CTR. guess the surfers knew what they were gonna get so didn't bother to click thatgirl.
