I think I didn't explain this very well. What I meant was: at Web time,
we'd roll the dice to see if it was time to update the stats. If it is,
we do /one/ extra query and /one/ extra HTTP call. We could do this at a
fixed probability (0.1%, say) or be a little smarter about it.
For identi.ca, say, we do 500K page hits per day, so if we want to post
about 20 stats per week, we'd do:
20 stats/week / (7days/week x 500K hits/day) = (20 stats/week) /
(3.5M hits/week) ~= 1 stat/100K hits
...which really isn't going to be a big problem for users.
