Twitter can be great for keeping in touch with friends or keeping up with what’s going on in the world, especially trends in technology and breaking news. Twitter attracts a lot of Web-savvy users, but it isn’t really meant for kids. The ability to post anything you want can get kids in trouble if they say something in the heat of the moment. The service’s location-sharing features also make it too easy for kids to post their whereabouts, which can lead to face-to-face meet-ups with strangers. Finally, some tweets in the site’s Moments section sound like plugs for various TV shows, and Twitter allows kids to receive tweets directly from celebrities they admire, such as sports stars, actors, and musicians.
