Tweegee.com's Zones are a great place for tweens to flex their creative muscles. There's a wide palette of options for customizing the Zone, including design elements, polls, an event calendar -- even a statistics tool that measures visitors and unique visitors. The filtered chat feature -- which also governs Zone content and most other text fields -- has an excellent vocabulary, so safety shouldn't get in the way of self-expression.

But The Buzz leaves something to be desired; most of the stories are fluffy stuff that tweens can find elsewhere, and some of the product write-ups seem more "advertorial" than news. Also, visitors who stop by The Cinema won't find much variety as most of the videos are promos for video games or violent "classic" cartoons, although the Tweegee tutorial and safety videos are definitely useful.
