About one-third of British youth aged 14-21 who are online at home have their own blog or website, according to The Guardian. This age group spends about eight hours a week online, with about half that time spent in online communities or IM; another hour is spent on e-mail. The poll suggests six in 10 have net access at home. They download an average of three ringtones per month for their cellphones and spend five hours a week on video game consoles. Tip to SmartMobs.
