This service charges GPB 200 for 5 Mio clicks. Drupal.org served 7 Mio
pages in July only, so we'd need some money to spend on this.

as in beer. Also, the free thing only covers one page.

Sure, but as has been pointed out: We'd retain control of our own data,
so I'd prefer it if somebody who has both skill and interest writes such
Furthermore, as has been pointed out by me, drupal.org is a large,
untapped datamine. If we make sure the data is properly anonymized, we
can certainly use that data. Unfortunately, nobody seems to have more
than passing interest to exploit the data.
So I don't see a point in accumulating more data by installing a
non-free script which stores our data on somebody else's server.

You can easily determine this from our own accesslog data. We store the
referer and the destination of each click. So, if the referer is /node
and the destination is /project then I clicked on the corresponding tab.
In most cases there is only one link for a specific destination on one page.

Ok, this you cannot get from our data.

I think the results would not be very Drupal specific, actually.

To get an aggregate, you still need to store the individual events. They
especially list prices for stored clicks, so I guess that's what

You should extrapolate from your own customs to everybody else's.

Anybody interested in doing this? I will happily provide the data.
