…to impress the boss, a client or room-full of curious suits. Then you might want to look at this social media presentation from Stefano Principato posted to Slideshare earlier this week. It has a little of everything, including graphics that detail:

• the growth of social networks
• Twitter and Facebook usage patterns
• user profiles by social network, including age breakdowns
• consumption/sharing habits of all of the above.
• graphics on social networking usage in society, plus geographic breakdowns.

Think of it as a chart-of-the-day in 39 slides. Grazie, Stefano, for putting this together.
