"It's about being organic, man", it's about not starting a community, but inviting people into our everyday lives and seeing where it goes. Every "community" that I've been involved in, that worked, had a natural organic growth with ebbing and flowing of people count as well as direction. Some have continued on past my involvement, others have not. Death is natural. That's okay. I think it's in our desire to control that we lose control.
Sorry, I'm having a hard time summing up my experiences, without using ethereal examples.
But I stand by the statement of opening up your everyday life to people, they see the good, the bad, and the ugly. Then there is no shock down the road. It reminds me of watching my boy play yesterday. He walked up to a boy playing in the dirt he'd never play with before. He stated his name, age, and that he wanted to play. When conflict arose, they stated what was the matter, it got worked out. An hour later when we had to leave, they parted ways having had some fun.
My two cents
