So says a new infographic courtesy of Imbue Marketing, which combed the Net to breakdown the user profiles, their likes and habits of the biggest social networks today including YouTube, Pinterest, Instagram, Facebook, Twitter, LinkedIn, Foursquare and Google +.

An interesting new piece of research came our way late yesterday from Porter Novelli looking at the social networking of European consumers. The research points to a few important distinctions that can be made from the individuals within the online crowd, namely that women predominantly use social networks to make and maintain personal connections while men Tweet, post, update their networks with opinion and to display status updates. There’s also an important distinction to be made around brand loyalty.

Brands and companies using Facebook for feedback is not news – every day fans are asked to rate items, or are encouraged to chat about new launches. But how often do brands take these comments on board in creating new products? Japanese carmaker Nissan aims to do exactly that in its ‘Project 370Z’, which will see the brand’s Facebook fans crowd-source a special one-off, track-ready, 370Z using off-the-shelf performance parts and accessories.

The biggest social media hiring coups of 2012 so far goes to Kraft Foods which managed to lure B. Bonin Bough, former head of social media at PepsiCo, away from cola giant. Bough, who was the face behind PepsiCo’s enormously successful Refresh Project, is expected to run digital comms/marketing at the food giant which is going through a big shakeup itself this year as the company splits into two parts. Bough has plenty of experience championing digital and social within a massive organization as he told us two years ago at our SMI 2010 conference.

Well-known in the UK for its migraine-inducing TV commercials (subject to no end of techno remixes) featuring Barry Scott screaming at the camera in front of a background of lurid colours, cleaning brand Cillit Bang has gone online, where it’s no less, ahem… in your face.

Coca-Cola has set down a marker for CSR and sustainability communications through its Arctic Home collaboration with WWF. The centrepiece, up until last weekend, was an interactive online site where fans of Coke who made a donation to Arctic Home were able to enter a virtual Arctic environment and track polar bear sightings while corresponding with field scientists.

A ranking of the City’s most social savvy firms was released this morning and the results may very well surprise you. (They certainly surprised us.) Carnival, the embattled cruise ship line, Burberry, BP, Marks & Spencer and ARM Holdings scored in the top five of the FTSE 100 Social Media Index.

P&G has been pioneering clean water schemes for seven years, and estimates that its patented powdered purification technology has saved 22,000 lives through the purification of 4 billion liters of water.

Attracting bright young recruits has been the focus of HR professionals at the world’s largest companies for well over a decade now. It’s been the subject of flashy magazine articles that look at Google’s free lunches and Apple’s compensation plans and the cool factor of working for Facebook (the impending mega IPO there helps). There’s also hope for smaller firms looking to stay competitive in the talent wars: using social media for internal communications.

This year’s Super Bowl saw five times as much social activity as last year, figures from Trendrr suggest, which is not surprising given research by Coco-Cola showing that at least 60 percent of viewers were expected to have a smart phone, tablet or computer within arm’s reach and that an average of 10,000 Tweets per minute were fired off in game’s final three minutes.
