Worldwide Buzz & IM

Jure Leskovec and Eric Horvitz, released an interesting study about Microsoft Instant Messanger network population: demographics, attitudes, etc...

Here is a chart about demographics, compared with the world population: "ages 15-30 are over represented in the Messenger user population"

Here a map about "most active lines of comunications"

Two more evidences:

"a strong influence of homophily in activities, where people with similar characteristics overall tend to communicate more with one another, with the exception of gender"

"...we find cross-gender conversations are both more frequent and of longer duration than conversations with the same gender"
