<strike>Bearing in mind the Ubuntu philosophy that Ubuntu is for everyone. Would it not be appropriate to reason that Ask Ubuntu is for everyone?</strike>  
If on reading a question that could be personally described as too broad by the reader the reader does not have to answer it.  It is askers choice to ask.  Readers choice to answer.  The community then will decide how appropriate question is by using the many features of Ask Ubuntu.  
Going by the answers to this question maybe this question could be considered to broad and is an example of different people reading the same paragraph will see it slightly different.  Just as the same if there were two witnesses to any event - both accounts would be different due to a differing point of view!?  
***FAQ is guideline not concrete law!***  
EDIT:Perhaps making a signed Ubuntu Code of Conducts together with reading FAQ a prerequisite in order to access Ask Ubuntu would provide a better way of introducing new users to what is acceptable and what is not.  
After reading fact it is not allways easy to put the theory into practice.  There is clear concise advice on how to use comments for example as weell as plenty of questions in meta highlighting the need for people to change their habits so as to improve the quality of this Q&A site! Another point of interest that i found helpful in FAQ is remembering to bring sense of humour and found these helpful in remembering that i have one http://meta.askubuntu.com/q/2042/102029 and http://meta.askubuntu.com/q/2281/102029  : p
