I once ran the numbers for HN and was surprised at how closely they matched this rule. Maybe I'll do it again. Edit: here are some estimates. We don't track enough to know about distinct users, so all we can do is guess.

How close that is to the '1% rule' depends on which is the bigger facto…
Any way to divide logged in weekly sessions by all weekly sessions, or something like that?
