I can appreciate that you need to run adverts on the site.
However, a lot of the adverts are really obtrusive. I've had some which are overlays of almost the entire page, requiring me to close them once the close icon has appeared and some smaller ones which pop up in the middle of the text but are drawn very slowly and even after they've been drawn the close button is not available until a second or two later.
Most other sites I read frequently don't use such adverts - can you stop doing so as well? All they serve to do is annoy readers.
