A wiki that anyone can edit?
I'm concerned about the elitist, self-inflicting, mini police-state that has evolved around Wikipedia/Mediawiki administration, and all the ongoing noise about banning (see the support mailing lists for endless necessary discussions not possible within Wikipedia).
So long as any admin can ban anyone, especially as a resolution to a fight they themselves are in (or even started), there will be a nasty undercurrent of negativity and fear to the Wikipedia/Mediawiki experience.
Wikipedia is not free and open to all.
We all know banning is bad for the one banned.
What few understand is that banning is also bad for the person who bans, and the community, makes us callous and full of ourselves as superior and elitist, and becomes a "Shoot first, permit no questions" police state, whenever an admin feels even slightly uncomfortable or challenged.
Admins do not see themselves as service support staff, here to help everyone, anyone, and Wikipedia/Mediawiki is the worse for it.
I will always see Wikipedia/Mediawiki content and community as full of holes due to the missing contributors, intimidated contributors, and compromised contributions from play-it-safe contributors, so long as Wikipedia/Mediawiki has not developed a work around to prevent banning, and to encourage admins to help, not hurt.
Love and hugs,
