The impact of online on offline behavior.

Nature - international weekly journal on science published a mass social-network study which shows that influence of close friends raises participation.

Just how much can activity on Facebook influence the real world? About 340,000 extra people turned out to vote in the 2010 US congressional elections because of a single election-day Facebook message, estimate researchers who ran an experiment involving 61 million users of the social network.

Map of Online Communities

Came across this map of Online Communities. Thought it was worth sharing. I am doing research on how different age groups spend time on the web in different geographies, which sites do they visit, percentages of time spends, etc, and how does this behavior change with age. Any information / past research on the same is very welcome. In the meanwhile enjoy the Map of Online communities.
