That's not entirely true. Whatever article I am reading in instapaper is an article I have visited in a normal webbrowser first, with all their ads in place.

That's not entirely true. Whatever article I am reading in instapaper is an article I have visited in a normal webbrowser first, with all their ads in place. Then decided I didn't have time to read it at that moment and clicked the instapaper "read later" bookmark, but by that time I have already seen and ignored your ads.
