The 'Who Tweeted?' infographic discusses the way in which fictitious followers end up on Twitter and influence major accounts.

Including a brief history of the social network, the chart goes on to talk about which celebrity Twitter accounts have fake followings, and why that may be. Though many accounts have followers who aren't real, some, like Mitt Romney's, stand out. Romney's account had particularly suspicious activity, like gaining 17% more followers in one day from accounts that were less than three months old. Though certainly a clever public relations move, strategies like this give Twitter users a false account of what's happening on the site.

Sure to wake people up to the reality of online networks, this chart is a must-see for social media enthusiasts.
