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?
Cool :)
Does that mean after about 300 days after account creation, people give up
at editing?
No, the average time before people abandon their accounts would be much
shorter. Many accounts have never edited at all, I imagine there are also
many accounts with only 1 or 2 edits. An average over accounts would be
skewed towards this end. This is an average over edits, so it is skewed
towards very active editors.
One interpretation would be to assume that most edits are performed by a
core group of very active editors. Then you could say that the average age
of a very active editor is about 300 days. You have to phrase it carefully,
because there are two factors which limit this figure: attrition and growth.
Editors getting tired and leaving will cause it to be reduced, as will an
influx of new editors.
What would be really nice is if we could get a handle on these two factors
separately.
