The given example of a now nice questionexample of a now nice question on ubuntu-one is also a good example to discuss on how far we should go when it comes to support U1 (or get supported by U1).
In the first place (go through revisions) this question was neither tagged ubuntu-one nor in any other way remotely reminicsent of the way we are used to ask herehere. I was very impressed how @dv3500 turned it good and interesting indeed.
I do feel that this may be a better way to handle these kinds of questions than just closing them as it may keep people happier with Ubuntu on the long term. However there are questions that ask for closing. It would be unfair to treat U1 questions differently.
