I have the my homepage set to a wikipedia random page so I learn something new every time I start firefox (the url is “http://en.wikipedia.org/wiki/Special:Randompage“). And today I got this wikipedia article amounts to not much more than an advert. It demonstrates some of the flaws of not running it through a gatekeeper I think, but given that I have been using wikipedia for ages and haven’t run into many problems like this, maybe their dispute resolution does work well. But I suspect more and more people working in PR/shills will start to manipulate entries.
