Re: How Launchpad does it: merge proposals, on-call code review, EC2 automated testing

Tomasz, if people find it valuable, we'll definitely consider it. I'm most
interested in investigating other projects who deploy onto high-traffic
websites, and have relatively high-speed code review, merge, deploy, and
release turnaround. A few places where we could grab ideas:
* OpenStack (I believe Ryan Lane mentioned that they integrate substantial
volunteer contributions into an Agile process)
* Mozilla (they successfully ask all contributors, including volunteers, to
submit tests along with their patches)
