This would also discourage peeping toms, people who like to watch but not be watched.

I'm all for having everybody be able to watch everybody else, since I think the wikipedia community should be as transparent as is reasonably practical.

However, I think you allusion to peeping toms is totally overblown and slightly absurd. By the nature of the act itself, posting on the wikipedia is a public act, with public consequences, and therefore it cannot reasonably be considered private. While we allow a certain degree of anonymity, the wiki is by nature a public space, and so nobody is invading the private sphere just by tracking which articles someone edits.
