A great fora of numbers
For sometime I have watching how the numbers of people in our forums stack up against other distros. While no number should ever be taken in isolation, together they can probably yield a pretty good idea of how big the community is around each distro.
First I took the top ten or so distros on Distrowatch. I discarded Suse, Slackware and Debian as they did not have alarge centralized forum. Of those that were left, Mandriva, Mepis, Damn Small, Knoppix and Xandros had smaller forums, by any count. This left Gentoo and Fedora.
Gentoo has by far the largest forum of any distro, but this might be due to a large number of users/developers being of the forum culture (as opposed to the mailing list culture that is Ubuntu and Debian).
Fedora and Ubuntu forums stack up pretty much equally when you look at all numbers except one. Fedora typically has about 6 times the number of currently active users as the Ubuntu forums, with the vast majority of those being guests. Very odd. A better statistician that myself will have to explain that.
