We have very few people editing the wiki. I doubt there are eminent issues with edit wars, but I think this is primarily because people who disagree with things on the wiki don't care about the wiki.
For example, if "someone" decided their Loan strategy advice should definitely be on the wiki, and insisted on editing it in, would it potentially cause an edit war? Or take any strategy disagreement you can find in ample supply on this forum and consider if both sides had active investment in the wiki, what happens?
We are fine. Nothing needs to change, but in theory I don't personally agree with it.
If there are valuable (subjective) things on the wiki that aren't anywhere else, I'd consider that an argument for posting those things on the blog, not for keeping them where they are.
