What if the install program randomly invited 1% of users to join popcon?
"We want to make sure that Ubuntu suits your purposes. To do this it
would help us to know what software you use. Do you agree to
automatically provide this information to Ubuntu?
We will not store personally-identifying information as we only use
this information to determine the popularity of different software
packages supported by Ubuntu. Only 1% of users are invited to this
The obvious disadvantage would be that it introduces non-determinism
into the mix, which may mess up some forms of scripting and users that
insist on following step by step instructions exactly.
The obvious advantage is that it gives us sample as unbiased as
possible without mandatory popcon, while still adding only 0.01
mouse-clicks to the average install. Perhaps the submissions to popcon
that come from the specifically invited people could be marked as such
so that we could keep the relatively unbiased sample pure, and compare
it to the sample of people who actively hunted popcon down.
