This article give a just just amazing example of group forming.
… excitement died down, Wallace, now living by himself, was overcome with loneliness and ennui. On a whim, he took out a classified ad asking people to “join” him and send him their passport photos. That was it. “I was just interested to see whether people would,” he later recalled. “And then I forgot about it.”
Much to his delight, someone joined. In fact, a whole posse of someones. Wallace quickly exceeded his goal of one hundred joinees, and set his sights on one thousand. Collecting them became like a fever. Wallace bounced around Europe, appearing on late-night talk shows and in newspapers to spread the gospel of Join Me. He began meeting with his devotees and taking them out for beers. He set up a Web site and even recorded a theme song, all the while trying desperately to keep his burgeoning secret life hidden from Hanne. But then Wallace’s adventure took a new turn: The joinees began demanding to know what, exactly, they had joined.
In fact, they rapidly became irritable with their Leader, who was always mysteriously vague about what it was they were supposed to be doing. They sent plaintive e-mails, and posted theories on the Join Me Web site Wallace had set up, speculating that he was doing some kind of weird statistical research, or perhaps was a “demented megalomaniac” on a “massive ego trip.” One of the more enterprising joinees created his own Web site and agitated the others into pressuring Wallace to reveal what Join Me was all about.
Mutiny was afoot. Wallace knew that if he didn’t come up with a point, his career as Leader was over. “I would be lying to you if I told you there wasn’t a part of me that wanted to use my joinees to spread mischief across the land,” he later wrote. “But alas, it wasn’t to be. Because I, Danny Wallace, was to be in the service of All Things Good.”
So the Leader decreed that the point of Join Me was this: to be nice.
That’s got to be the best example of a community founding myth I’ve seen.
It suggests that the three markers of a community (common: cause, ritual, responsiblity) can arise after the group forms. 90% of the founding myths are are about a bunch a guys who discover a problem and then band together in common cause to address that problem. In this myth the group forms and then demands common cause. Like a bunch of kids sitting around going “I don’t know, what you want a do?”
