Here's a bit of incidental info about zope.org mailing list subscription that may (or may not) be interesting to some of us. I've been collating it weekly, using a python script i made to go through the mailman subscribers log. I suspect the charts are structured a bit unconventionally - it may take a bit of effort to understand what they're saying. The instructions are below - i'll just note a few key concepts: - Each entry (line for a week) indicates the change in subscription activity for that week. - The stuff in the '+' side indicates the *net* gain in subscriptions - those above the number that are cancelled out by unsubscriptions. (Instead there's a '-' side in those rare cases where unsubscriptions outnumber subscriptions.) - The stuff in the '.' side (either plus or minus) indicate balancing pairs of subscriptions and unsubscriptions - which rob recognized as being the "churn". - When necessary, the charts are normalized (to fit in the alloted space), in which case each tick represents more than a single subscription action. - The totals may not jibe with the actual subscribership of the represented lists because some of the lists predate the mailman subscribers log file (from which the stats are derived). I may someday spend a bit more time to log these things somewhere on the web site, for visits by anyone with interest (as they might web log displayers). Not immediately though - not high enough priority. (Pardon me if the chart formats are obscure - they're really tailored to my particular purposes, and may not be obvious in general...) (And pardon my mania for character graphics - i confess i really enjoy seeing what can be done within such wooly constraints...) -----.----- *>=====[_]L) (<= i dunno know who made it) -'-`- Ken Manheimer klm@digicool.com -=- -=- -=- These charts convey the flux in subscriptions of the following mailing lists: <All> zope zope-announce zope-dev zdp zope-packagers zope-checkins digicool-cvs How to read the charts: Each chart covers the weeks from the start of the mailman subscribers log to the current date. (Each week sample begins on sunday, so the first and last week samples may cover less than 7 days.) The curves themselves depict two things for each week: - The net gain or loss in subscriptions for the week, and - The "churn" in subscriptions, ie the number of new subscriptions that are cancelled by resignations All stats are indicated with character ticks around a centerline normalized for each graph: - Net gains are indicated by '+' sequences to the right of the centerline, - net losses by '-' characters to the left, and - churn by '.' sequences, on the opposite side from the week's net coup. The numeric magnitude of the respective gain/loss/churn is indicated by numbers at the extreme positions of the sequences. Since the sequences are normalized to fit in the width of a page, some of the ticks constitute more than a single subscription (gain/loss) or subscription pair (churn) - that factor is indicated with a note at the top of such graphs. It's important to note that the figures for the net changes are just the net - for a week with a net gain, the total number of subscriptions would equal the net plus the churn, while the number of unsubscriptions would be the same as that of the churn.
