Social Infographic – Facebook vs twitter

Digital Surgeons recently posted an infographic – Facebook vs Twitter. The most interesting data is the differences between Age Group, Education, mobile logins and brand followers. Both sets of users(fb and twitter) have a low percentage of brand following, however it would be interesting to see the data on word of mouth/mentions of brands that occurs on the two services as I am sure it would be higher than the direct engagement(following/liking/fan). Also I query how they measured or defined a login as many people use desktop or browser app programs to login to twitter and facebook.
Infographics are becoming more and more popular, however we are often left asking how the data was collected and the rigorousness of the analysis. The digital surgeons infographic gives great data in instantly referencing form.
