At the first stop for the Hyatt4Good Tweetup Tour, I talked with Adam Hirsch of Mashable. The tweetups are part of Mashable's larger Summer of Social Good effort. Adam, COO of Mashable, explains what the Summer of Social Good is all about and what lead up to it. The tour will be making stops in several cities this summer before returning to New York to host the Social Good Conference.
