Yes, that would be interesting to know, but what I am thinking of is
more like:
When a person becomes "active" (by some definition), how long do they
tend to remain "active" (by that same definition).
I would say looking at this in a variety of ways would be useful. Anons
pose special problems in interpreting the data, of course, and so
probably we won't get much useful information out of those. But since
we know that almost all people who are really part of the community get
a user account, I suspect that looking at the activity patterns for user
accounts would be the most interesting.
