You can go on kidzbop.com! It is like youtube and myspace! But it is just for kids. There is also fbfkids.com (Facebook for Kids) and for little kids there's fbfkiddies.com (Facebook for Kiddies) kidswirl.com also!
Poptropica and Club Penguin are two.
It's ccalled FurTag. It isn't as good as facebook though.
There is a website called Kidswirl.Its kinda for kids though...

No.Facebook is mainly for adults to meet with their old friends and to make friends.
for children aged about 7-9 www.fbfkids.com is a good one but once you get the age of about 10 it gets very boring. for kids aged about 9-13 www.kidswirl.com is good until you get to the age where you can actually join facebook.
facebook has alot of games kids like games
