I was particularly struck by this quote:
Mobile devices now account for 13 percent of worldwide Internet traffic, up from 4 percent in 2010.But what does "traffic" mean? Not all traffic is created equal.
I'm especially thinking about the fact that this article is, itself, absolutely *surrounded* by junk when I read it on my desktop. There are ads, links to other articles, a survey, social-networking connections -- all sorts of crap that is almost entirely uninteresting to me. I'd bet that that junk makes up 90+% of the bits on the page. Mobile sites, by comparison, tend to be leaner if they are well-designed -- on a small screen, you just *can't* have all that junk taking up space.
So here's the question. If mobile traffic is 13%, but is much more content-focused than desktop traffic, what percentage of actual *information* is going over mobile? It seems certain that it's more than 13%; I'd be fascinated to see a study that tries to suss out actual numbers...
