New social media stats from Nielsen: Tumblr #2 in UK, FC2 #1 in Japan, Tuenti #1 in Spain

This week Nielsen published its new quarterly social media report. It's a useful piece of work to take a look into and well worth a read for all the rich stats and facts. Some findings worth pulling out include: 

• The UK's 2nd biggest social network is now Tumblr, with 229m page views, behind only Facebook
• In Spain, people spend more time per person on Tuenti, not Facebook
• Orkut is #1 in Brazil and FC2 Blog is #1 in Japan
• Twice as many people aged 55+ are using mobiles for social media compared to last year
• Females aged 18-34 are the most active demographic on Facebook

Thanks Nielsen for making this report available to all online.
