Thanks Erik. Good question. I address that question a bit sharper than I planned in part II. On a more personal note, I see critique as help. Thus an opposite voice can be seen as help. Training attitudes, such as openness and trust as prerequisite can help very much within closed groups. Trust can be build. Thieves and liars are a different problem. With open groups, like Occupy, where freeloaders helped downgrade the whole drive is much harder. In his book ‘Tribes’, Seth Godin argues that at some point it may be smart to exclude new members. Create a strong culture first. (If you know the Dutch Permanent Beta Festival you can see how they try to only attract the ‘right’ kind of people) Seth describes a cycle, where positive cooperative people start something up, and then the wolves come in, eating for free. Then one creates either more and more rules, killing the spirit or the cooperatives leave to start up somewhere else anew.
