No. 6: Stephen Colbert
Until recently Colbert followed no one, which made perfect sense from a character perspective. Then former President Bill Clinton appeared on The Colbert Report and received a lesson in the ways of Twitter from the host, who uncharacteristically felt compelled to follow the former president’s temporary account, @PrezBillyJeff. Today Clinton has a real Twitter account, which follows eight others, six of which are organizations. The two humans? Clinton’s daughter Chelsea and Stephen Colbert.
