Yikes!
The Wikimonster takes yet another victim!

A long time ago, people thought that what was true was what someone who knew said was true.
A bit later, someone said it had to be in accordance with the world to be true. Adaequatio ad rem, and all that.
Later still, it was changed to "true is what conforms to observation in most cases". Truth became a statistical matter.
We apparantly left that stage behind us, and moved on from "most cases count" to "most votes count".
A Wiki is an example of that, with an aditional clause, saying that the access to internet and time to spend editing wikis adds to veracity.

A Wikipedia article as a reference?
Fy on you!
