Social Networking By Age

I saw an interesting chart recently. It showed social network site users by age. Here are the stats:
75% of 18-22 year olds use one or more social networking sites
49% of 23-35 year olds
21% of 36-49
9% of 50-65
3% over 60

I personally use Facebook. I have really enjoyed connecting better with family members, particularly more distant family members, and all the friends and acquaintances from places we have lived and worked around the country. According to this Pew Research chart, I am among 9% of my age group that does this. For me, it seemed pretty natural to launch into social networking because I have always tried to stay up with technology as it has developed at such a rapid pace. I must admit, however, that I don't have a Facebook farm, I don't look for eggs, I'm not a Mafia member, nor any of the other myriad of opportunities that are available. I just enjoy the posts and pictures and all the "catching up." I was thumbing through a college catalog the other day and wondering about taking a computer networking class.
