We do like a pretty chart around here, and these latest ones from Nielsen are positively gorgeous. The internet stat-keeper has come out of a particularly hot and heavy research session with the conclusion that American online habits are a-changing. The unstoppable juggernaut that is social networking (23 percent) leads the way on computers, with online gaming (10 percent) now joining it in second place, and email ousted to an unhappy third (8 percent). The slack in electronic postage is being picked up by mobiles, however, with 42 percent of cellular internet time dedicated to exchanging messages the old fashioned way. Video streaming has shown double digit growth relative to last year, but remains a comparatively small part of what US interneters do. One thing we find humorous in the data is that 34 percent of all web time spent on computers is bundled into Nielsen's "Other" category -- any ideas on what people might be doing during that time?
