Why do non-techies simply not "get" the idea of a wiki?
geuis: The problem isn't the idea of the wiki. It's the implementation. Any non-techie gets how to write a blog post in Wordpress. Spacing, make things bold, etc. I've been editing with various wiki software for years and I still find it cumbersome. If you can have a system that is a wiki under the hood but has a normal-person level interface, you would see more usage. Regular folks have better things to do than learn our odd syntaxes for doing things. It's not something that saves them time because instead of being easy and automatic, they have to break their trains of thought to do this "wiki" thing. It's no different than when your coding in the zone and your manager interrupts you about something marketing wants.
