Mark Zuckerberg’s dad, Edward, is a dentist in a suburb of New York City.
As you might guess, Edward is big into promoting his practice through social media.
As you might not guess, he doesn’t restrict himself to marketing through Facebook.
For example, his Website, PainlessDrZ.com, is actually built on Tumblr’s platform.
(Apprised, Tumblr CEO John Maloney says, “Hah! That’s wonderful.”)
Dr. Z is not so much a fan of Foursquare, however.
Asked if he would use it instead of Facebook Places to market his practice, he told the LA Times: “If Foursquare were a better product?”
“I’ve never been faced with that problem.”
