I know that my mother (apart from being a teacher, a very normal internet user) also has quite a few tabs permanently open, but that's mostly facebook and similar sites; she spends less time reading long articles than I do. In other words: This is a problem that mostly power users who shifted all of their reading to the web face. I, for example, now only read about 6 physical books a year, but spend a lot more time reading online. I probably read the equivalent of a small book every day, it's just that this happens in the browser and thus instead of stacks of unread books I have heaps of unread tabs.
