My internet isn't the greatest, so as macrumors starts loading, I start reading. The text shows up, then it keeps jockeying around until the ads all load, making the stuff I was trying to read jump down the amount of space the ad took up, Making me search out where I was. Can't a web page know the dimensions of the ad spaces and and put the text in the right place the first time so that the ads just load in their set aside spaces and nothing jumps around while I'm trying to read it?
