Are Baby Boomers Killing Facebook and Twitter?

The story is as old as the Web: A social network born among twenty-something college kids and young wired professionals sprouts up, apparently out of nowhere, and grows into a cultural phenomenon. Eventually, it reaches critical mass and explodes, its mushroom cloud drawing the attention of millions of Baby Boomers, leading to a huge influx of new users, which in turn triggers complaints from the youngsters who started it all. The invasion of the Boomers spurs some members of younger generations to flee the carnage (and the fallout) in search of fresher territory. We've seen this scenario play out on MySpace and Facebook, and now it is starting to happen on Twitter. When the Baby Boomers--traditionally defined as anyone born in the United States between 1946 and 1964--arrive, they tend to do so en masse. And when they set up camp, they invariably change the dynamic of the social network itself. Whether due to their distinctive social habits or the sheer vastness of their demographic, a mass migration of 50-and-over folk brings in its train everything from increased political activity to a proliferation of spam.
