I think that works best; a moderator is / should be only a member that happens to be responsible for maintaining the site's user behaviour policy and tidiness of articles posted, and thus decisions shouldn't be an "I" or "we" thing, but "the site". Of course, that's an utopia and no amount of rules will cover every situation.

It may sound stupid, but it'd make me feel better if moderators still used "I" even if otherwise completely anonymous. Still add human touch and personal responsibility to the act even if there is no way to call some particular person out.
