Hi Dario, Reid,
This seems sensible enough and proposal #3 is clearly the better
approach. An explicit opt-in opt-out mechanism would not be worth the
effort to build and would become yet another ignored preferences
setting after a few weeks...
A couple of thoughts:
* I understand the reasoning for not using do-not-track headers (#4);
however, it feels a bit odd to say "they probably don't mean us" and
skip them... I can almost guarantee you'll have at least one person
making a vocal fuss about not being able to opt-out without an
account. If we were to honour these headers, would it make a
significant change to the amount of data available? Would it likely
skew it any more than leaving off logged-in users?
* Option 3 does releases one further piece of information over and
above those listed - an approximate ratio of logged in versus
non-logged-in pageviews for a page. I cannot see any particular
problem with doing this (and I can think of a couple of fun things to
use it for) but it's probably worth being aware.
Andrew.

I’m sharing a proposal that Reid Priedhorsky and his
collaborators at Los Alamos National Laboratory recently submitted to the Wikimedia
Analytics Team aimed at producing privacy-preserving geo-aggregates of Wikipedia pageview
data dumps and making them available to the public and the research community. [1]
Reid and his team spearheaded the use of the public Wikipedia pageview dumps to monitor
and forecast the spread of influenza and other diseases, using language as a proxy for
location. This proposal describes an aggregation strategy adding a geographical dimension
to the existing dumps.
Feedback on the proposal is welcome on the lists or the project talk page on Meta [3]
