Felipe, about you second argument, that not all bots are registered as such
that (or not anymore, it may change): yes that is a problem.
I can only hope that really active bots are caught and registered on large
wikis.
Many bots that are active on many wikis are not registered as such on
smaller wikis.
Therefore I treat any user name that is registered as bot on 10+ wikis as
bot on all wikis.
It is of course again an correction which is not 100% accurate, but close I
might hope.
Single User Logon can help in this respect some day.
In theory we could spot some bots by their behavior, say a user that edits
24 hours per day, of manages 5 updates per second for a long time, or added
thousands of articles in a short period.
But Im not sure it would be worth the effort, and it would low priority in
any case.

The bot share of all edits is not that insignificant.

Hi, Erik, and all.
IMHO, it would be a good idea...but not definitely an urgent one. In our
analyses on the top-ten Wikipedias, we found that bots contributions
introduced very few noise in data (to be precise statistically, it was not
significant at all).
You also have the additional problem that some bots are not identified in
the users_group table.
My "practical impression" is that when you deal with overall figures, then
bots are irrelevant. However, if you want to focus in special metrics like
concentration indexes then their contribution DOES MATTER, since a very
active bot in one month may ruin your measurments.
Regards,
Felipe.

Statistics,
with "Wikipedians",
"active" and "very active
users";
like often, Zachte's Statistics are great,
but
easily misleading.
Also keep in mind that most figures in wikistats still
include bot edits.
IMO it becomes more and more urgent to present separate
counts for humans
and bots.
For instance in eo: 54% of total edits for all time were
bot edits, but most
of these will be from recent years, so the percentage will
be even higher
for recent years.
