The result of the deliberation over the Enterprise 2.0 article in Wikipedia was a keep. You can see the archived discussion here. Despite all the fuss, I'm pleased with the process and the outcome.
Also, Optimize Magazine has a new piece on Enterprise 2.0, with the pros and con.
UPDATE: SJ:
As always, it amazes me that so many people -- homemakers, high school students, firemen -- who simply care about the development of a reference work can be as sensitive to nuance and level-headed in academic discussions as academics (who have devoted much of their life to scholarly discourse). It makes me at once proud and disappointed by our civilization; that all manner of subtleties can be picked up without special training; and that much capability is untapped through ignorance or denial of this.
