100,000 Kubuntus
If I read the Swedish mirror's statistics correctly that's almost 100,000 downloads of Kubuntu. 2TB of Kubuntu is a lot of Kubuntu. It even beats the Ubuntu downloads. that's because it's listed top on the kubuntu.org download page.
I have a filter in my .procmailrc file to send anything containing Kubuntu direct to my mailing list. In the last week I've been getting a lot of e-mails directly which would normally have gone to kde-bugs caused by bug reports referencing Kubuntu use. This doesn't mean Kubuntu is any more beastie ridden than anything else, it means we are getting a lot of users who then feed back to KDE (and directly to Kubuntu as appropriate), and that is good for everyone.
