I have a (sporadically-updated, I confess) blog about my two children. This BBC article suggests that maybe I should encourage them to take it up themselves:

Children as young as seven in one British school are using weblogs as part of their normal routine, and are doing better than non-webloggers as a result, their teacher says.

Weblogs, easy-to-use personal journals published on the internet, get children more interested in school work they might otherwise have disliked, says junior school teacher John Mills.

Children at Hangleton Junior School in Hove, Sussex, have been using weblogs in their spare time to learn more about things that interest them, but as a result their performance in class has improved.
