Older People on Facebook
Facebook began as a social-networking site for college students in North America.
Nowadays you are just as likely to find the parents of those students on Facebook. The social network has grown exponentially in the past two years and includes a high percentage of people who are over 40.
The site is used to find friends – including those you may not have seen in many years – and to update them on what you are doing now.
Today Facebook is the most popular social-networking website.
likely: a word used to describe something that will probably happen.
