[Balug-Admin] stats: list membership (~457 total uniques)

[Michael Paoli]

list subscribers (does include also those with delivery disabled):
$ wc -l */memb*`date -I`
   27 balug-admin/membership_2007-09-03
  264 balug-announce/membership_2007-09-03
  258 balug-talk/membership_2007-09-03
And a rough approximation of unique e-mail addresses (note that some folks
use unique per-list addresses):
$ sort -u */membership_*`date -I` | wc -l
457

Note also that it appears we have a fairly large number of folks that are
subscribed to "talk", but *NOT* subscribed to "announce".
Theoretically (at least logically) that shouldn't be the case
(in general - typically exceptions being per-list e-mail addresses),
but it is totally under "user" control.
A quick count of that:
$ { sort -u balug-talk/membership_`date -I`
> cat balug-announce/membership_`date -I` \
> balug-announce/membership_`date -I`; } | sort | uniq -u | wc -l
185
