Recently I've been playing with the recently released Foursquare self-service for managers tool to create and monitor campaigns for your venue. Before this, it was a manual process where the special would need to be submitted to the Foursquare team and you would wait anywhere between 3-13 days for it to be approved and go live. Now, once you select the details and the way a special is unlocked and hit confirm, the campaign is live automatically and you can start seeing it when you refresh your Foursquare app on your smartphones.
I played with this feature over the weekend whilst in Brisbane for a trade campaign which mainly targeted 12-20 year olds who were interested in the celebration of popular culture. I noticed a lot of holes in the learnings I picked up, including the number of people who had access to smartphones at the event, Foursquare's actual penetration in the Australian market as well as the expectations of how one should redeem the special.
