That's easy :
1st one is Windows, 2nd one is Mac OS X, 3rd one is Ubuntu and they are almost as popular as Ubuntu according to distrowatch, so they are 4th.
While that's a joke from me and I am in no way affiliated to linux mint and completely clueless on that point, I strongly suspect that's the real explanation.
Counting Windows as a single OS would be false IMHO, so I suspect that the 3 first place would me microsoft products ( xp, 7, and 2k8 ). That let OS X as 4th, and likely 5th, or vista. Then we can start to find various Linux distribution and based on my own experience at the lug and various events, Linux Mint is no in the top 5.
What amaze me is the number of comment on the blog, and the fact that no one question neither the stats, nor the whole business plan and the lack of detailed financial report ( cause 3500$ a month is enough to pay one person full time, and that's not negligible ).
I guess as Linux Mint has a distro based on Ubuntu and one on Debian it probably has Ubuntu or Debian in the string as well.
So we can't compare.

User Agent string is no longer a valid way to compare distros at all. Neither Chrome nor Firefox (circa Firefox 7) list the linux distribution by name any longer in the user agent string. The list "linux" and some cpu information now. I've personally made the wikimedia stat script maintainer aware of this change in the last couple of months.
Any linux distribution shipping officially branded firefox by default and conforming to the constraints that Mozilla places on trademark usage will no longer be differentiated in these stats. It's already started to impact the Ubuntu stats significantly in the last couple of months, There is an accelerated downward trend in "Ubuntu" over the span of several months that can only be reasonably accounted for by this user agent string policy change. I fear that people will misattribute the drop in Ubuntu wikimedia user agents stats I expect to see after the 12.04 LTS release as a reduction in Ubuntu usage. And that would be a real shame.

I guess that means distrowatch will in the future also not be able to differential. So those are also useless.

Distrowatch doesn't use client user agent strings. Distrowatch makes no effort as far as I am aware to tell what you are currently running as you view the site. It's strictly about which pages on their site are viewed by the most ip addresses every day.
