FWIW, fully a quarter of the screen is taken up by fixed position elements that are entirely irrelevant to a reader. When I see this on sites I want or have to use, I add cosmetic rules to delete the sticky elements. When I see it on sites I don't have to use, I close the tab.
I don't claim that this makes it a net loss for you from a money standpoint, nor that I'm representative of a majority of your market, but I _do_ suspect I'm the sort of potential customer that isn't easily studied in an A/B test.
If you're talking about that obnoxious left sidebar, I agree. The table of contents widget on the right too. The article itself is squeezed between a bunch of shit I don't want to look at. It makes the page feel crowded and like it's trying to get me. Please just let us read the content! If it's any good, it'll speak for itself.
