News for Nerds Roundup: Who's using Twitter? Facebook?

In this mostly uninteresting article, the NYT says:"Almost everyone under 35 uses social networks, but the growth of these
networks over the last year has come from older adults, according to a
report from Forrester Research issued Tuesday. Use of social networking
by people aged 35 to 54 grew 60 percent in the last year."

The NYT cites Forrester Research's new ($500!) study:"Social technologies continue to grow substantially in 2009. Now more
than four in five US online adults use social media at least once a
month, and half participate in social networks like Facebook. While
young people continue to march toward almost universal adoption of
social applications, the most rapid growth occurred among consumers 35
and older. This means the time to build social marketing applications is
now. Interactive marketers should influence social network chatter,
master social communication, and develop social assets - even if their
customers are older."
