Anarcopedia

The Anarchopedia .org is the first large public wiki to attempt to eliminate all sysop vandalism. In the start a policy that any registered user can undelete pages was declared, which in theory makes ad hominem delete no worse a problem than ad hominem revert. Currently the policy does not seem to be fully applied, which is understandable as it gives vandals full powers to wreck stuff.

Without this special power to prevent their opponents from reading the alternative view, it is thought, sysop power structure will not form at all.

Anarchopedia seems not only to embrace but seek to extend the NTPOV to all aspects of wiki governance and wiki management. There are no vile mailing lists and no cabal of friends with infrastructure owners trust as there is at Wikipedia.

It is also notable for embracing a one wiki model. It has some problems addressing language vs. area specializations.
