What people are doing online
I just found this fantastic information graphic from Business Week that demonstrates what people are doing online and is broken down by age range. I particularly like the categories used: Creators, Critics, Collectors, Joiners, Spectators, Inactives.
Looking at the Youth (18-21) column, social networking is the top activity for this group with 70% participating. I think this definitely supports the argument for “being where our patrons are.” At the very least, that we should be aware of where they are and think about how it informs their use of the web.
As an obsessive RSS & Delicious user, I find it somewhat difficult to believe that there’s relatively little activity going on in the “Collectors” category. Maybe these technologies just fit a niche need (the need to share links, need to have a central bookmark collection, the need to read way too many blogs).
