My soon to be 15 year old DD wants to have a twitter account. I am told that all of her friends have accounts and that no one uses facebook anymore. She tells me that she is not going to post things about what she is doing. She just wants to be able to follow celebratees and be in the loop with her peers. I am not sure this is a good idea. In the past, her friends and her have posted pretty silly things on facebook. There hasn't been any problems with facebook but I don't know enough about twitter. What do you think an appropriate age is for a twitter account?
