I can anecdotally confirm this and even place an age limit. My daughter (25) is an avid FB user while my son (17) is not. He has an account, just never uses FB except for the federated login. Seen this pattern among their friends too. EDIT: Can anyone explain what is causing downvoting? Are anecdotes not valuable information?
