"""I am not convinced that very many people care about discovering new events in the first place, at least not events that don't have an immediate impact on one's social status."""
My definition of an event is: A social gathering of my friends, or friends of friends. I don't care about random trivia nights, but I might check them out if my immediate friends are going to them.
I believe that an "event community" is a misguided notion. Going to the same event as a perfect stranger is not a strong enough context for socialization.
