Ubuntu is based on Debian!

Well it was another day, just like any other (or was it)...?
Heres an update, I have been using GNU/Linux for almost 2 and a half years now and im finally getting a little used to the Desktop Environments and the command line interface. I just recently switched recently from Debian to Ubuntu to give it a try. It sounds more promising than the Fedora core 4 I tried awhile back (on my Compaq Presario in between win 2K and win XP), as Ubuntu is based off my beloved Debian.
Much public interest (including a few friends of mine) have convinced me to switch my main SOYO computer to Ubuntu 5.10 (Breezy Badger). I'm also working on a dual-boot of windows XP and Debian on the Presario currently. Besides the easy curve of not having a root user account anymore (everything in Ubuntu is sudo commands) most things seem very much like Debian with a few welcome tweaks, twists, and new artwork. I have already also installed Kubuntu and Xubuntu Desktops and reset the few settings that had apparently been set to default when the settings files not in my /home/ folder were formatted in the root partition in the switch. My fault, but not a big deal to me whatsoever.
I also have been alpha and beta testing Mozilla software like Firefox, SeaMonkey, and Sunbird in both Linux and Windows. I'm trying to get a better understanding of how bugs are detected in software (smoke tests of nightly builds in this case) and learn how software is developed in general.
