Operation of a Large Scale, General Purpose Wiki Website - Contains some fascinating stuff, particularly in regard to geographic and chronological wiki searches. The brief wiki history and description of their own wiki is also interesting. I like his thoughts about meta-data. His discussion of the "comma count" as wiki page metric is new to me, but might be worth following up. Lars also writes that "In the case of a combined website that might feature both a wiki, a weblog and static contents, the same search function should cover all contents available on the web." which is a great idea, but not always easy to implement.
