The Interpipes Are Leaking of the Day: 36-year-old Columbia College journalism professor Dan Sinker, who was recently outed as the beautiful mind behind the infamous @MayorEmanuel Twitter account, got to meet his real-world counterpart yesterday afternoon at the WLS-AM 890 studio in Chicago. “Many times he has expressed my sentiments exactly,” Emanuel told listeners.

Mayor-elect Emanuel also made good on his promise to donate $5000 to a charity of Sinker’s choice, bringing with him a check made out to Young Chicago Authors — a nonprofit aimed at teaching public school students creative writing and performance.
