got a mail from LinuxQuestions this morning with a link to this site.

I am not sure how comprehensive this statistics are, but I do find the interesting.

I also saw, that the name Ubuntu only appears once (as 5th out of the 15 most popular distros). Not too much action in the last 30 days and it is unbelievable how many new releases have appeared after 9.04, which appeared... well ... just the other day, didn't it?
