That really just shows that you really didn't know anything about Ubuntu. Not that it is something to be ashamed of, but I'd expect that you had known that by reading the numerous Ubuntu articles on this site.
I wouldn't quite say I knew *nothing*... I knew it was originally developed on the Isle of Man (and assume it still is), that root does not have a password by default and you have to use sudo to do admin stuff (there's a way around that), I knew there was a lot more configuration that's done for the user right out of the box, apt is the path to updates, there's a growing user base, there's growing application support and the GUI is superior to standard GNOME and KDE (though I did not realize how much so). Oh, and the logo is kinda ugly IMHO. The main surprises to me were the size being so small and the base being Debian. I really thought it was an independently developed distro like Debian, Red Hat, Slackware or SuSE.
Now, all of this said, I have not worked enough with it to make a judgment on what I think of it. It's pretty, sure, but it's configured different than Red Hat and I need a Red Hat system for certification. Once I get done with the cert, I will give it a fair shake.
Its popularity speaks loudly for its support and usability. Can't ignore that.
