User, sysop and bureaucrat on it.wiki otrs volounteer with access to permissions (all) and info (it and scn) queues, trusted user on Commons, I have been global rollbacker and global sysop, since September 2011 I have been a steward. I'm often on the irc as Vito@freenode. I'm registered as Vituzzu on Wikimedia's projects only, I do not use this nickname on any other website different from those hosted by the Wikimedia Foundation. I'm used to break the Internet. If you want to troll the easiest way is taking advantage of my polemic side (which is seldom shown).
The original (I'd call it "genuine") wiki-model was similar to open source projects. Now Wikimedia is catching a social network-like "wiki 2.0"-model. I personally believe it would be unsuitable in building an encyclopaedia but, anyway, I'd appreciate someone for the Foundation clearly stating this new "vision".
