I recently flagged this answer. The question can basically be summed up as:
I want to create a Ubuntu live USB so I can install Ubuntu. How can I do it?
The flagged answer can be summed up as:
Don't. Install the Unity desktop instead.
To be honest I can't see how this answers the core question, i.e. how to create a Ubuntu live USB, so I flagged it as "not an answer".
The flag was declined and I would like to know: what is the motivation behind this decision?
How should I apply the NAA flag more precisely?
