Kit is of course correct. I confess that I didn't check Robert's URL
but assumed that it was a link to what Kit is describing. Not so!

On each web browser page, users are strongly encouraged NOT to download software this way (and that it will probably fail if they are Windows users). Nevertheless, a nontrivial number do so; this statistic might be termed the 'bozo count'. But those counts are a serious underestimate of download activity from the SSC Archive, as the recommended technique to perform these downloads is from within Stata using the -ssc- command, and a much larger number of Stata users download using this recommendation. Such downloads are not tracked by RePEc services, but they are tracked by the web server which satisfies Stata's requests. So the URL above should be removed from the "Popularity" document. A URL which gives a snapshot of download activity over a recent month is
