SXSW attendees may remember that both Gowalla and Foursquare launched at the aforementioned conference in 2009, and during its 2012 edition, the former is formally saying goodbye. Just three months after we heard that Facebook had picked up (but two months after the shutdown was promised), Gowalla is saying its final words. Specifically: "Thank you for going out with Gowalla. It was a pleasure to journey with you around the world. Download your check-ins, photos and lists here soon."Don't cry, Gowalla -- at least you won't have to deal with any more SXSW registration lines.
