I'm at Barnes & Noble and I pass the "In the Media" table, and what do I see but a Snakes on a Plane movie guide. I pick it up and what do I see on the first page that I flip to? A SoaP tribe -- complete with a screenshot and some text about it.
From the book:
A dedicated traveler on the information superhighway, Medusa first learned about the existence of Snakeson a Plane on one of the several messageboards she keeps tabs on. And, after doing some research and figuring out the movie was the real deal, she created her own "SoaP"-dedicated space on Tribe.net, a service that builds Web-based communities through friends near and far. But Medusa's site wasn't simply to pay heed to the "Snakes" experience. No, her plan goes one step further than that. She wants to develop a movement that will have people attend the first screenings of the movie... in groups... dressed like snakes.
...
As of mid-june, she has forty-one signed-on members of her Tribe, including people she didn't even know. And while she has no idea how many of them, or how many more, will go all-in on this experiment in fun, she feels a responsibility to make it as easy as possible for those who want to take part to do just that. Accordingly, Medusa plans to introduce a section that will offer costume advice.
