If after reviewing 60 some ads I only keep 6, it would seem to me that the intelligence in the Google ad selection algorithm is somewhat suspect. If I don't block those other 54 ads, I WILL see them on both local and remote computers and I have to suspect my visitors will as well.
My sites all serve a niche revolving around art history - if the ads aren't about art... they're gone. It's the only reason people come to visit. Ads about house painting, powder coat systems, wedding portraits (while having legitimate value) are likely not what will interest my visitors.
And it is also with that in mind, that I try to minimize interest based ads as much as possible. Event sites like Meg's can easily be enhanced with IBAs but it doesn't work the same for mine.
While I'm not sure that shutting off IBAs in Ad Serving is completely effective, my stats do show fewer are served than when they're enabled. And yes, Ad Review has no connection to IBAs as far as I can tell - can't imagine how it could.
