One of the coolest integration stories we have is the tie in between Ask Ubuntu and developer.ubuntu.com, which enabled us to build a pretty impressive library of q+a for application developers. You can find all of this in application-development.
Jokerdino reached out to some people another area of ubuntu development, which is development of ubuntu itself. Traditionally in the project this has been called "Ubuntu Development", but it tends to be confusing to people because for some that is packaging, for some it's fixing bugs, and so on.
David Planella recommended to me that we should start off with platform-development and symlink packaging to that, and maybe other tags (perhaps patch or whatever other thing relates to fixing ubuntu itself.
That way we have one tag for people who want to ask questions about developing ON ubuntu, and one tag for people who want to develop Ubuntu itself and it would give Ubuntu developers one tag to subscribe to to answer Q+A about working on Ubuntu.
Why symlink packaging to platform-development? Well, the experts in packaging in Ubuntu are MOTU/ubuntu developers/debian developers. I want to have one tag where they can subscribe to. Sure there will be some questions where someone will want to package something that won't want to contribute that to the community, but having one tag that I can tell them to subscribe to outweighs the semantic details of people's intent.
Thoughts?
