In Law School Innovation: Should law schools be developing legal wikis? Doug Berman links to Robert Ambrogi's article Legal Wikis Are Bound to Wow You, and also says this:
I could readily imagine having a class project centered about building a wiki (my death penalty class blog this past semester has some wiki-like facets). I also would readily approve a student independent study project that was wiki-centric, and I certainly could see student organizations and law reviews working on wikis as an integral part of their activities.
That sounds like fun.
