ESPN (http://espn.go.com/)

Brimming with features, the site boasts so much info for kids that many may not even feel the need to move onto the ESPN.com SportsNation message boards. Indeed, the boards seem to be relatively on-topic and clean, and there's a "report violation" option on every post if anything does appear that is against the site's stringent rules. Yet there are some hard-hitting topics like doping, racism in sports, and other politically and ethically charged discussions that less mature teens may not be ready to engage in without guidance from a parent.

Fully registered users can create a MyESPN profile to customize the site, have conversations with other users, and create a profile and blog. But this, too, has a safer privacy feature built in for the younger users or anyone who wants to keep it private.
