I hate sites that are eaten up with advertising, so I've tried to keep ads to a minimum and tucked away in corners. But I'm experimenting with some different ad placements, which I've told will perform better. So you'll see some banners under the titles of articles and forum posts (but not each individual comment). You'll notice that I've removed the ad blocks that used to be in the right-hand menu.
I hope these don't annoy anyone. I'm going to try them for a few weeks and see if they do better at these locations than they did at the previous ones.
