Yes there is a Twitter for Kids the website is www.juniortwitt.com is a website that is property of www.myjuniorbook.com . Both websites are for kids one is similar to Twitter and the other one similar to Facebook. Take a look juniortwitt.com is just starting so there are not that many members myjuniorbook.com already has over 10,000 registered kids. Enjoy!
I like fbfkids it's facebook for kids it's cool for like kids 9to12 I love it there is chatting blogging making groups and more the site is still being fixed but check it. It's not like twitter but it has this on the wire thing where you post what you r doing, and if you like it tell your frendz about it
FACEBOOK is better than twiiter in some ways MYSPACE and BEBO are newer sites than FACEBOOK but there alsome I think they should make MYSPACE for kids even FRIENDSTER is better than twitter my kids are 15,13,16 and have all they least twitter than any other site.
