First, it gives you a template to post in - you are not given a blank page and told "document this"

Second, it encourages you to document single, smaller, focused pieces of information. You're not being asked or expected to write a multipage document, you're being asked to write a single entry in what essentially is a crowd sourced FAQ.

One thing the SO approach also does is that it respects the content that each person posts. If I post an answer, only I can modify it. Nobody will modify my answer to reflect what they think, and make it seem as if I was presenting a different solution that what I suggested. What people with alternative ideas CAN do though is post alternative answers, or comment on my answer with suggested changes.

Teams users won't be able to edit answers?

Here's how we coach moderators on the internal Stack-like site we run...

Editing

When editing content written by others, do so with respect to the person who is the original author of the content. Correct simple spelling and grammatical errors, but don't rewrite whole sentences or restructure some else's document. Instead, post a comment suggesting changes or corrections.

In his post here, he kind of directly writes that SO is not like a wiki.

"Because unlike wikis.."

When most people think "wiki", seeing answers before questions is certainly a common characteristic they could assign to the concept, but it's not what makes it a "wiki".

I could design a wiki that was text-only and say, "unlike wikis, we don't present photos", but that wouldn't make it not-a-wiki.

I'm actually kind of excited about the idea of an internal StackOverflow. Of course, people would have to actually use it, and that battlefield is littered with the shattered corpses of a million productivity and communication and social tools.
