Hello AoIR, I'm working on a project about various social network sites and I'm looking for updated data about Pinterest, G+ and Foursquare. I already found old global stats but at the moment what I really need are demographic and usage information (both global and nation-based, in particular italian and european ones) about the current situation of these SNS (or at least not older than few months). Can anyone suggest or recommend a trusted and updated source? Thank you so much: any help will be surely welcome. -- Fabio Stefano Alla Dipartimento di Comunicazione e Ricerca Sociale Sapienza Università di Roma
