In "A Generation Serves Notice: It's a Moving Target," from the New York Times, the author talks about current technology usage:
Among those with access to the Internet, for instance, e-mail services are as likely to be used by teenagers (89 percent) as by retirees (90 percent), according to Pew researchers. Creating a blog is another matter. Roughly 40 percent of teenage and 20-something Internet users do so, but just 9 percent of 30-somethings. Nearly 80 percent of online teenagers and adults 28 and younger report regularly visiting blogs, compared with just 30 percent of adults 29 to 40. About 44 percent of that older group sends text messages by cellphone, compared with 60 percent of the younger group.
Assuming that none of us are teenagers, I guess that makes those reading the SLA-IT blog part of an interesting minority.
