The wiki is entirely ready to go; all it needs is more contributions.
It also needs a long-term hosting, so that you can safely link to it, and not worry that the target URL will go away or get abandoned.
Another solution would be to support wikilinking in the markup language; that way if the wiki moves the links can move with it.
This is too hard to enforce outside the wiki, where anyone can fix failures to conform.
The greater convenience of the wiki markup might be enough, though?
