Social network Gowalla has officially closed its doors, posting a farewell message on its homepage, thanking users for their interaction.
Facebook acquired the site in the close of 2011, making it seem likely that its services will be incorporated into the social giant at some point. Gowalla is/was a location-based network, so perhaps this move was to help Facebook compete with the somewhat popular Foursquare. Gowalla was already going head-to-head with the similar service, so its competitive experience in that social market will no doubt come in handy.
The message on the Gowalla site reads: "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."
This message will likely give a bit of relief to any members of the site that were worried Facebook would simply swallow up their data. Instead it seems that they'll soon be able to download it in some fashion - though you'd imagine people would have retained their own copies and not just trusted it so some random website.
Gowalla was just one of many acquisitions by Facebook in 2011, including mobile ad firm Rel8tion, Beluga group messaging and Mailrank for its email prioritisation services.
