Everyone is moving into this method. It will most likely prove effective to actually get click throughs on the ads, but still, it makes the site ugly. I do a lot of web design, mostly for private business, so there are no ads required, but I can't say that I would agree to a full site overhaul with floating ad shells. It even took the blue color scheme out. I am all for a face lift every now and again, but just for the ads? Ouch. It really puts the website in the background, literally. Pirate Bay started it about a month ago, now you can't even hide the random, creepy cartoon porn ads that always pop up to both sides. They just stay there, floating, no matter what you do. Pirate Bay and swellinfo are two completely different things.
Welcome to M'erica. I ain't mad at you dog. Money is money though. Stack that cheddar.
