*Very simple way of putting it by summarizing [Flimm's answer][1] and merging it with [my comment][2]:*

## Development is ontopic, provided...

 - ### it's related to Ubuntu (to at least some extent) ###

 - ### the user has some reason to not post it on SO and mentions why. ###

Note: users are expected to be aware of the existence of StackOverflow.
