Forget "Mad Men", now Bernbach is on Twitter

At the risk of declaring that Twitter has jumped the shark, now I've gotten an invitation to follow Bill Bernbach on Twitter, in a move probably inspired by the "Mad Men" twitterers. Bernbach seems confused by Google's new browser, Chrome, and is trying out the Avis "We try harder" slogan on anyone who will listen. Seeing Bernbach on board gave me the idea that maybe I should start impersonating David Ogilvy, but somebody already thought of that, and the Twitter D.O. even claims to be having dinner with Betty and Don Draper on Thursday night. Maybe I'll be Mary Wells. Anyway, this whole Twitter impersonating thing probably has jumped the shark. While I was putting together this post, I got an invitation to follow Dr. Benjamin Spock, who is following more than 700 people but hasn't posted a damn thing.
