Togetherness under a wiki is all very well but... it doesn't really last, does it?

Consider these wiki examples of what begins to happen:

• Users abuse the concept of what "the community wants" to promote what the user in question wants; every other wiki user is made to look an idiot
• Major contributors are not only unsupported but are hounded off the site because they are too *something* that the other users are not (*Insert: useful, helpful, sensible, innovative etc.)
• Laissez-faire responses to users who offer help; ending up being ignored or fobbed off
• Many ideas sitting in the wiki in-trays unfulfilled
• Ideas misused and inhabited by those with their own agendas and more power -"more power" on a wiki, you say? Yes! Power play is wiki too.
• Admins infight and undermine one another
• Domineering users take over the entire site, teach all other users to suck eggs and never look in their own nest
• The police force arrives - "thou shalt not" becomes order of the day and the police force begins to wield its heavy batons; everyone becomes subject to order and wiki goes on vacation
