With Rosetta out the door (and evidently quite popular), Canonical has quietly launched a piece of system called Launchpad.
I spent much of the Ubuntu conference in Mataró, where there was much chatter about the imminent release of launchpad, slightly amused by conversations about the mechanics of "launching Launchpad."
It centered around an interesting question that is either a matter of philosophy or engineering depending on how one looks at it:
How the hell does one launch a launchpad?
