Can we glean from the access logs on wordpress.org the number of times the nightly build has been downloaded? If it can be broken up by day (or some other over-time grouping) going as far back as is reasonably feasible, that would be great.
The nightly build is located at http://wordpress.org/nightly-builds/wordpress-latest.zip.
We are planning to release 3.5 tomorrow, so if it is possible for this to be done today, it would be appreciated, as it could inform us of our next steps.
Perhaps we can/should send that link through dl.php and do stats tracking on it, once 3.5 is over.
