How does your long involvement with debian conflict/compliment your work on Ubuntu?
Ubuntu keeps me very busy, both personally and professionally, which means that I don't have much time to devote to other free software projects such as Debian.

So much of what we do is inspired by what Debian has accomplished. My history with Debian also means that I'm better able to relate to the needs and perspectives of Debian developers, which is critical in maintaining that relationship.
