The wiki navigation column is a bit weildy at the moment but when yo think about it, it's a partial remedy (if populated accordingly) for the wiki dead ends texrat mentioned.

I was toying around with a subpage where I had shamelessly appropriated wikipedia's front page and was adapting it to contain the wiki's front page. It might be worth considering if Intro and the wiki's front page couldn't effectively be merged. As a bonus, that would help set the wiki front and center to community knowledge management.
