I would be fascinated if we could figure out such statistics as
"For any given edit, what is the average length of service of the editor?" "For any given edit, what is the median length of service of the editor?" These could be measured by either time since first edit, or total number of edits or (perhaps best) some weighted average of the edit history.
Turns out we can.

Average was easiest, so I did that as a first try. It shows an initial upward trend, stabilising in early 2005 at about 300 days.
How's that?
