A) Should we value editors with many edits more than editors with just a few?
Your counter-example (editors who write a long article in one go offline) is
canonical, and probably uncontested, so you're stating the obvious, no need to
use a loaded term like 'offensive', and to spell it out as if WereSpielChequers
wouldn't know this, or would disagree. I use the term 'core community' loosely
myself from time to time, knowing full well that any precise definition would
be incomplete. Incidentally I think 'very active editors' is a misnomer (which
I started) for the same reason. People can be very active editors offline per
the same example. 
B) Agreed, we should be careful to interpret a trend (-change) in a very basic
metric, or what that metric actually tells us anyway. But again I think you're
stating the obvious. The only thing that surprises me is your timing: I never
heard you utter these nuances so much when veteran foundation staff and other
core community members overemphasized (in my opinion) countering editor decline
as a primary target (I tried to nuance this all along as much as I could).
So yes, 'editor count' is overly simplistic, and so is 'inflation rate', 'gross
domestic product', 'population count'. All of these are overly simplistic, and
without further breakdown don't tell us much. Yet these simplistic metrics
survive, because everyone understands them, and much less people want to know
the underlying complexity (especially decision makers), and importantly: they
are collected consistently for a long time (more refined numbers suffer more
easily from definition creep, or being en vogue temporarily). The most refined
metrics are often from one-off studies, valuable but not gaining enough
momentum for repeated collection.
I need to explain my statement which was re-quoted in this thread: "The growth
seems real to me". I first and formost meant "To my best knowledge the numbers
are reliable". I expect no bug or other artefact (WereSpielChequers asked me
about that specifically). The code is time-tested and stable. There is always a
change that a hidden bug surfaces in a changing environment, but I see no sign
for that. So at face value the growth is real then, more editors pass the
threshold. But giving meaning to that figure is a process of never ending
Lastly, a more philosophical comment: shouldn't we rejoice if a partially
understood metric seems to give ground for optimism. IMO we should, as joy (and
fear) provide the incentive to dig deeper. Our news agencies make a living of
incomplete news. Any scientific knowledge is temporary at best, until
falsified. I rejoiced when I read that traffic accidents decreased in last 5
years.Then someone countered that road traffic declined overall due to dip in
economy, so the effect may be temporary and not systemic, so I lost some joy.
But I gained from the exchange.
 I would be interested to see how often this happens: writing an article
offline in one go. My hunch is less and less, as more and more people get
speedier access, and site submits happen faster, thus reducing 'involutarily
 Specifics on the examples you gave:
I find some of your examples in your first mail a bit far-fetched. Very active
editors reversing each other ad infinitum, hmm, when was the last time you
actually saw this? And (spam)bots are excluded from out editor counts anyway as
much as feasible. In general edits on wp:en grew in 2015, while reverts stayed
more or less the same: https://stats.wikimedia.org/EN/PlotEditsEN.png
In your second response you name some positive reasons why our editor count
could be growing, and they seem mostly plausible to me. But here is also room
for nuance: 'Faster load/save times make the site feel more responsive and so
people can do more edits in the same amount of time.' would be high on my list
to investigate, and maybe even be reason to question the gain. The uptick in
January conincided with a major site performance boost (faster PHP). I can
imagine people who edit heavy articles like 'Obama' (heavy in terms of links
etc, with iirc almost a minute of submit time), would edit online in one go
without intermittent submits, and now these same people went back to
precautionary intermittent submits, thus accomplishing same amount of work in
more edits, in which case our gain would be mostly our editors' peace of mind.
Building on this: perhaps part of the decline in previous years came from

Subject: Re: [Wikimedia-l] Increase in size of the core editing community
For enwiki, whose stats I happen to know best, one might say the bottom was
actually around mid-to-late 2013. The plateau and subsequent modest upward
trend was visible first with occasional/new editing metrics like new active
editors (>= 5 edits per month), but has since also appeared in measures of
highly active editors (>100 edits per month).
This timeline would suggest that at least some of the change predates what Lila
put in place, though her team may deserve credit for the continued improvement.
In 2015, we are also poised for something of a transition. The cohort of
editors who registered on enwiki in 2006 have made more edits to enwiki than
any other annual cohort in every year from 2006 to 2014. If you choose any
edit at random since 2006, the most likely year that the account registered was
2006. That cohort, a legacy of Wikipedia's great growth period, has had an
outsized impact on enwiki editing for nearly a decade.
(2005 and 2007 cohorts also have a strong pattern of continued editing, though
not as huge as 2006.) If current trends continue, the 2006 cohort will finally
lose their crown in 2015. The 2015 cohort is likely to make more edits in 2015
than the 2006 cohort makes in 2015. It will also be the second year in a row
that first-year accounts have increased their total edit count, after seven
earlier years of declining edit totals for first-year accounts.
I think there are plenty of reasons to be modestly optimistic. I'm not sure we
should every again expect dramatic growth, but if we can move towards a more
stable or slowly growing community that would seem to make an apocalyptic
collapse less likely.
