I really dont mind ads, if I can tell they are ads (I'm not that stupid, I know they are ads.) But, I really hate ads that are "disguised" as parts of the web page. These actually look almost like posts, the one is see is describing an 8800gt, but I put my mouse over one of the links, and it says (in the status bar) basically that its going to send me to what looks like another post at techpowerup, but it takes me to zipzoomfly.. not that thats a bad thing, but why not just tell me that in the ad.
I REALLY hate those double-underlined words that pop up as you scroll down and accidentally put your mouse pointer over then, then you have to either "x em out" or WAIT FOREVER for them to go away, as you try to read something behind them. I don't care what they are selling, I don't even look or care whatsoever. They have pop-up blockers, are there "double-underlined word blockers"?
I'd rather look at a nice, tasteful, banner ad at the top of the page. Thats the problem though these days, it seems like nobody has any taste. As long as it isn't another "kill the mosquito" or "click your mouse as fast as you can for a free car". I'm a lot more willing to click on an add if I actually know where its going to take me before I click on it, I like ads with information I guess, not stupid gimmicks.
