Below is a cool infographic I came across today from Social Media Benchmark. It was done in late 2011 with what businesses and marketers thought about the social media growth for 2012. It contains info on who is managing the accounts, how often they post to the different networks such as facebook, Twitter and Linkedin.
What I found interesting is Pintrest is not shown. I believe the primary reason for this, is because that Pintrest literally took off in 2012, growning faster than any social network has in the past. Check out the infographic and let me know what you think!
