Just tried to read a thread and the sliding post is covering and concealing the entire OP. I can get to the rest of the thread, once I've scrolled past the huge annoying bit in the way, but there's no way to get rid of the wretched ad to be able to read what the original post was about.
From an advertising point of view, I have to say I'm not building good associations with these products, I'm more wanting to throw things on sight of them..... rather like that wretched woman and her ruddy chocolate cupcake.
