I cofounded a social discovery company a while back, so have thought through similar issues. Consider a dating site -- at the minimum, it must laboriously onboard a number of users at each location. Your site faces a much more difficult challenge -- you not even need lots of users per location, but you also need them to be continually posting events. I encourage you to consider how to add value to users even when there is no constant stream of events (and perhaps even when there are few other local users).
