[[Special:Unreviewedpages]] and [[Special:OldReviewedpages]] show the number of user having the page on their watchlist, which would be very useful to identify "high-risk" pages where it is easier to slip through a vandalism or a biased edit - if only it would actually correlate with the number of users watching a page. The problem is that only a tiny fraction of the accounts are "real" users, most have already left the community a long time ago, or never stayed in the first place.
A much better metric would be the number of *active* users watching the page (where active could be defined as edited in the last N days, or maybe logged in in the last N days).
