Foursquare is poised to become a member, along with Twitter and Facebook, of the social-media "pantheon" -- but it's not there yet, writes MG Siegler.

"Simply put: Foursquare needs to change their game and needs to do it soon if they want to keep the momentum alive," Siegler argues. "They need to keep users engaged or they run the risk of becoming the Friendster of location."
