Dunbar's Number

I loved this short film that asked one simple question: "What Does 'Community' Mean To You?". As Maria points out there are some (perhaps expected) universal needs that seem to emerge including proximity and convenience, face to face interaction but the over-riding need seems to be for a sense of belonging.

Twitter’s approach to easy social connections lets people build big networks, often quickly. Celebrities attract millions of followers. Even non-celebrities can develop many thousands of friends; some resort to automation tools to build their following more rapidly. But what do all these connections mean? Clearly, one can’t interact with all these people on a regular basis. New research shows that there’s an upper limit to how many truly interactive social contacts we can handle.
