When can we expect the clicktracking data to be available?  You
mention "users"; do you mean registered users?  Were anonymous IP's
considered to be a separate class of users, or were they lumped into
the "monobook skin" numbers?  It should be obvious that hiding
interwikis for users who are not logged in should be based on data of
users who are not logged in and thus do not have a preference they can

Also, I am interested in what clicktracking is occurring, whether the
data is being anonymised before being put into the hands of the
usability team, whether appropriately anonymised data will be
available to other researchers, etc.

This was mentioned briefly on wiki-research-l.


I recall similar functionality being _explicitly_ deactivated on
English Wikipedia as soon as Matt Bisanz brought it to the attention
of the English Wikipedia Arbitration Committee, yet the above says
that the data was taken from English Wikipedia!


The UsabilityInitiative extension is enabled on most wikis; e.g..


Is clicktracking now occurring on all WMF projects?
