I dump articles into instapaper send them to my kindle when there's a pile of them. That's usually every week. Then, when I have some free time, waiting for my beef stew, for instance, I'll chip at them little by little.<p>Some really short ones --- a short news for instance, I just skim over them when I see them.<p>Some articles require more concentration, and I'll usually add them to my At-Desk to do list. When I'm at my desk, and has a chunk of free time, I'll pick one and read.<p>One thing is that over the week, some articles will have the same topic, with varying depth and quality. So by waiting a little bit, I can often read less words while still being informed.<p>But I probably spend much more time on books, mostly in mornings and evenings, because I prefer books in general. However, I read fictions most of the time. It's probably not what you have in mind, and it isn't really comparable to articles.
