Now, we all know a Wikipedia page doesn't have the weight of other sources and can be crap at times but so far it's a total class act and it has a lot to do with these policies.
I'm sure you know that Wikipedia has to constantly police itself for large companies trying to mess with competitor's pages and how there are armies of political operatives out there trying to rewrite history through Wikipedia. This is why even experts like the OP are so scrutinized.
