The social media 'Cosby Show'
Superstar social media use, exhibit A: Bill Cosby. Already an established Twitter pro, conversing with 3.6 million followers, he's now dabbling in Instagram. He's off to a rather slow start there — just three photos this month. But a guy who calls Twitter "the best fan-to-entertainer exchange I've ever had" can probably figure it out. Find him on both social networks as @billcosby.
