But these contain so many variables too (did people still have
gnome 2.24 when the patch came out? Did people actually use the

Yes - I agree it is a quagmire of uncertainty :-) In a world of
(wonderful) 'zypper dup' - if we measure ISO downloads do we loose a
chunk of our most clueful user-base ? there are too many imponderables.

All in all, I think there are no unbiased variables - so there
will always have to be a decision made if the data we can get
is representative enough or not.

True; I like the live CD install / update data because it avoids (post
11.2) the bias caused by having a default pre-selected, and shows a
clear choice. [ can we detect the install / update of a live-CD vs. a
DVD install ? ] - it seems the clearest, most easily measurable proxy
for the choice during the installation flow that I can see.

Just out of interest, I queried the logs of last week for live cd redirects
(I dare to say that in august we see mainly people not already using

5323 IPs downloaded KDE4
3492 IPs downloaded GNOME
1791 IPs downloaded both

So - to unreasonably extrapolate from this small sample, in this random
timeframe I would turn that into:

rough percentage of download sites:
50.2% - chose KDE4
32.9% - chose both
16.9% - chose Gnome

from which - it seems, extrapolating, that we are needlessly annoying
1/3rd of DVD users by having a straight choice in that dialog rather
than check boxes (which can be made an orthogonal issue to having a
default - we can have both).

Of course, we need a longer sample run from a more sensible time, and
more thought - but it seems a reasonable metric to me - though clearly,
actual live-CD install numbers would better. Clearly we want to best
align all communities motivations with the process of installing
millions of new seats of openSUSE :-)
