This seems more like an aggregate solution for major social apps than a tool for locating local events and gathering spots. You get lucky if someone happens to be at an event you want. Cybernettr, the app I’ve found closest to what we want is called CalendApp. It’s not been updated in over a year but it still works relative to the amount of input it gets. Their Facebook page states something big is coming…but that was announced in Nov 2013! Still, it’s worth a try.
