To Wiki or Not To Wiki

You might not believe this (due to the general lack of scenery system documentation) but I do spend some brain power thinking about X-Plane documentation for third parties!

Consider two approaches to documentation:

• http://scenery.x-plane.com/
• http://wiki.x-plane.com/

My question is: which of these approaches is more "readable" or "clear" to you as a third party? Each one (the formal website vs. the Wiki) has pros and cons, but I can't judge "usability" of the documentation myself.  Is it easier to find things on the website?  On the Wiki?  Comments welcome!

(I need to decide where to put future documentation, hence the question "which works better for those who read the documentation.)
