The biggest mistake JzG has made on Wikipedia, the one that people should really be looking at closely, was his reaction to The Register stories in December.
This is described at the foot of this Wikipedia Review blog posting here. JzG's wild overreaction had him attacking people all over Wikipedia and the internet, and included the now infamous "Piece of shit Register story" attack. His attacks were accompanied by several disparaging references to Cade Metz, the journalist who was covering the stories, and obviously reading every word.
This totally unprofessional and self destructive flurry sealed Wikipedia's fate in the eyes of the media in one foul swoop. All the editors, all the articles, Jimbo Wales, the WMF, Wikia, everything was up for grabs as a result of that stupid, thoughtless attack.
Metz immediately shot off another article to the million or so readers of that magazine. And then peeled a Wikipedia Review thread about Jossi Fresco straight off our forums to hit them again in the New Year.
The media realized that stories on Wikipedia corruption brought in readers. And where better to get them from than places like the Wikipedia Review? Journalists were investigating stories from here for themselves, and figuring that many of them held up under scrutiny.
By the time ValleyWag was linking to one of our threads about Rachel Marsden, after Wikipedia had so successfully shot themselves in the foot again and again since December, Wikipedia was easy pickings for the media.
Yesterday, Cade Metz wrote another piece, which accurately depicts Wikipedia's predicament. It articulates exactly what Wikipedia Reviewers have been telling Wikipedia for a long time. But they didn't listen over there. Naive folks like JzG kept attacking and attacking, until Wikipedia resembles an open corpse. Food for the vultures.
JzG publicly personified Wikipedia's inability to process external criticism. And everyone on the site, from the best editors to the worst administrators, have paid a heavy price for this appalling attitude. The price will be the cruel and relentless public discrediting of all their hard work in the coming months and years at the hands of an uncaring media.
In the future, when historians look at Wikipedia as a bizarre 2000-2010 phenomenon that eventually collapsed, they won't be putting the blame on external Websites like us. Or critics like Daniel Brandt or Jon Awbrey. They'll be putting the blame on naive people like JzG, who positioned themselves as tub-thumpers and opinion formers for a community who didn't ask them to do so, and who brought it down on themselves and everyone else involved.
