You can watch the App Developer Q&A live stream starting at 1700 UTC (or watch the recording of it afterwards):
Questions should be asked in the #ubuntu-on-air IRC channel on freenode.
You can ask me anything about app development on Ubuntu, getting things into the Software Center, or the recent Ubuntu App Showdown competition.
Damn, I missed this. Too bad it was posted on G+ only like 2 minutes before hand.
Depends on who you were following, I posted it 20 minutes before hand. The video was also recorded, so you can still watch it even if you missed the live session.
You right!
