"Reuters reporter Alexei Oreskovic recently authored an interesting blog post about the demographics of Twitter users. What he discovered was that 18-24 year olds, the traditional social media early adopters, are actually 12 percent less likely than average to visit Twitter (Index of 88). It is the 25-54 year old crowd that is actually driving this trend. More specifically, 45-54 year olds are 36 percent more likely than average to visit Twitter, making them the highest indexing age group, followed by 25-34 year olds, who are 30 percent more likely." - AJ Kohn from Bookmarklet
