BSDStats.org sent out a summary of reporting hosts; there’s about 2,000 FreeBSD users and almost nobody else on other architectures. There’s only one DragonFly user reporting in North America, which I assume is me.

I just ran the script on my machine as it failed to run as scheduled (missing stuff in /etc/periodic.conf) so now you have company.
