"Today, Twitter is now the second-youngest of the top four social networking sites. Its median age is 31. MySpace's is 26, LinkedIn is 39, and Facebook is 33," says the site.
In fact, an academic and author is saying that we're seeing the end of social media that hits only certain age groups - in other words, Twitter isn't just for thirtysomethings / Facebook just for teens and so on:
"Craig Watkins [is] a University of Texas professor and author of the book "The Young and the Digital." He says that what we're seeing is "...a kind of closing of that generational gap as it relates to technology." In other words, young and old alike are joining the same networks and socializing in the same spaces."
If you're like me and get asked about the importance of one community over another based on the demographic then the Pew stats will come in handy for campaign planning.
