> I appreciate ads when they actually tell me something I didn't know about that I do want to buy.

I can't remember the last time I even saw an ad that did this (at all, not just online).

Oh wait, I lie, I do remember -- ads for electronics and computers in the technical journals of old used to do this, because they included actual information about the products they were selling. I haven't seen a useful ad in decades, though.
