i'm not usually a defender of donald rumsfeld, but i don't know how anyone could resist trying to edit a wiki page about themselves. the entire idea of wikipedia is that the editing function is open to everybody. doesn't "everybody" include the subject of the page? sure, rumsfeld is biased when it comes to rumsfeld. but i suspect that most other people who would be contributing to that page would be too. the philosophy behind wikipedia is that while individuals are biased, the crowd will fact check itself and lead to something resembling objectivity.
i don't believe that's actually the case. but if you do believe in wiki's open source experiment, i don't see how there's anything wrong with rummy participating.
