I think that wiki is great to keep things live and up-to-date. There are examples of very well organized wikies that perfectly complement normal web sites. See
The Tcl'ers Wiki or
Extreme Programming.
I would like to see OpenACS/ArsDigitaACS/OpenNSD/AOLserver wiki that would be what Tcl'ers Wiki is to www.scriptics.com or tcl.activestate.com.
It would be nice to change wiki implementation from CGI program to some more efficient implementation. But I belive we could start with CGI as well.
