I agree wholeheartedly that you're wasting your time.

If you'd care to explain how this feature will enable us to estimate the number of gnome users worldwide I would be very happy to hear it. The crucial bit of data, percentage of users who enable the checkbox, will be unavailable. Of course it will give you a lower bound, but so will any number of methods already discussed.

If you want to use the popularity-contest information to make an estimate which is just as bad as the one we could make with this "feature": take percentage of debian popularity-contest users who have GNOME installed. Multiply by percentage of debian users with popularity-contest installed. Multiply by debian market share. Multiply by linux desktop market share. Multiply by number of internet users.

Note that in this chain, all the numbers can actually be estimated, unlike the crucial "percentage of users with the count me feature enabled". The second one (percentage of debian users with popularity-contest) could be estimated by analyzing server logs on debian update servers when a new version of the popularity-contest package is released, and track the percentage of users performing updates who also download the new package (this isn't perfect, but its at least a good approximation, though there is likely bias in the frequency of user updates and liklihood to have popularity-contest installed).

The other numbers (the market share numbers) are available from any number of research firms, and all have their own problems in determining it. And of course the total number of internet users is at best a guess, but we can leave out that step and just use a percentage.
