Arno Ghelfi for Businessweek reports on who's doing what online, separated by age. The grid aesthetic totally works for the Internet theme, which can feel robotic and bit-wise at times.
From top to bottom are the more active users to the more passive. Age groups run left to right. So as we sweep top left to bottom right, we see the younger generation who is more likely to write blogs and upload videos to YouTube, to an older crowd who are more likely to be content consumers.
Update: Doh, this is from 2007. This cross-country move is throwing me out of wack. Oh well, it's still an interesting piece of Internet history.
