Facebook has been around since 2004. I have been a member since 2005. It was initially just for college students (that’s when I joined), followed by high school students. They just opened it up to the public in the last year so that’s why a lot of people (ahem, older folks) are just discovering it. It actually has a huge amount of members, especially in the 18-25 demographic. However, because it has been closed off, it’s overall numbers and overall hits with the 25-40 demographic is lacking compared to MySpace.
