Ah that's an interesting site, but note how the data is collected.
This site publishes the statistics gathered from report send by users
of the popularity-contest package. This package sends the list of
packages installed and the access time of relevant files to the server
weekly. So it's an opt-in sub sample of the population.
There is some useful data to be had here though, since its essentially a
subsample of the population we might be able to test against the ppa
numbers to estimate how many people who download actually use qgis on
regular basis.
#name is the package name;
#inst is the number of people who installed this package;
#vote is the number of people who use this package regularly;
#old is the number of people who installed, but don't use this package
#regularly;
#recent is the number of people who upgraded this package recently;
#no-files is the number of people whose entry didn't contain enough
#information (atime and ctime were 0).
#rank nameinst vote old recent no-files
4147 qgis6979 803 5903 271 2
I read this as 12% of downloaders use on a regular basis, of course that
may actually be higher for the ppa, since it takes extra work to enable
the ppa. It's also unclear if the ppa is included in this sampling method.
Thanks,

Question came up today of how many QGIS users are there. Since the
downloads happen from at least 4-5 major sites
(kyngchaos,osgeo4w,launchpad,elgis,qgis.org) of which only one is
directly a QGIS server the numbers are obviously short.
Doing some digging there's a new api addition for launchpad that lets
you get the data (soon to show up on the web interface too). The stats
aren't quite there yet, pending full web log scans on launchpad's side
but I wrote script this afternooon that is ready to start pulling the
data as soon as it's there. Example csv output is up to, just with
obviously wrong numbers.

Inspiration was from this ticket
https://bugs.launchpad.net/soyuz/+bug/139855
Just thought this might be of use to others. QGIS team, Tim and I talked
about working this python script into the Django site so we can list the
number of Ubuntu downloads anytime we want and aggregate it with other
stats we have.
Thanks,
Alex
