Location. People always ask me what the “future” of social media is. I think that where we are will continue to evolve, but we’re seeing that face-to-face connections have a role in social media marketing as well. FourSquare, Gowalla, Loopt, and other location-aware services are social networks, unifying real connections. Beyond that, though, there’s the potential for businesses to run with special promotions, bringing more people to a business location and maybe even cultivating new friendships as well.
