Launchpad is Ubuntu's bug tracker. The oldest bug is bug #1, from 2004, and remains unresolved. The comments section is still used as a chat area.

(This comment is now quite famous.)

Notes:

I'm on Ubuntu now on my home laptop and it is easily the best operating system I've ever used.

Bug #1 was linked to from Mark Shuttleworth's blog recently.
