The number of downloads of Prune has increased steadily over the months as the program has become more useful and better publicised. Some landmarks:

November 2006 - downloads exceed 10 per month
April 2007 - total downloads exceed 100
August 2007 - downloads exceed 100 per month
January 2008 - total downloads exceed 1000
October 2008 - downloads exceed 1000 per month
January 2009 - total downloads exceed 10000
October 2009 - downloads of version 7 exceed 10000
May 2010 - downloads of version 10 peak at over 100 per day
August 2010 - total downloads exceed 100 per day
October 2010 - both Debian's and Ubuntu's popcon tools show more than 100 installs each
March 2011 - total of Debian's and Ubuntu's popcon tools show more than 1000 installs
There are a few reasons why these numbers are horribly inaccurate. Firstly, they may underestimate the real number of downloads because of alternative distribution methods, other websites offering Prune downloads, downloads from linux package repositories, people emailing or copying the files around. But more realistically they hugely overestimate the number of downloads from this site because of crawling bots, because of people downloading the file more than once, and as I recently discovered, because the webalizer software also counts log entries with status code 206, which isn't a real download, it's a partial download. So if a client takes several requests to download the jar, webalizer unfortunately counts this as several downloads. I can only assume that this is a webalizer bug.
But, even allowing for the poor accuracy of these absolute numbers, they're still useful to look at the increase in the number of downloads - it's clearly showing a continual increase in the popularity of the program.
Most popular versions: version 7, version 12.*, version 11.*, version 8, version 10, version 9.
Most popular months: August 2010 (release of version 11), September 2010, May 2010 (release of version 10), June 2010, May 2011, April 2011, October 2010.
