i created and abandoned a project gathering developers not to do anything. people odly understood :) there was going to be a yearly newsletter that was never send out and participants were free to do other equally unimportant things together using the name of the org (that was never picked) overal it was a hilarious experience. most of the work was in assuring people they would not be contacted for anything.
If you write a negative book about a collection of topics and make it diverse enough not to have to go in detail you can tailor it such that wikipedia becomes the perfect promotion vehicle.
