I agree, it seems that the hordes of fans that Ask Ubuntu has sometimes make use of their close votes in a unfair way.
The help section of the site clearly states:
- Using and administering Ubuntu, including official Ubuntu derivatives.
- Development on Ubuntu.
This does mean that questions like: "How can I do this using Ubuntu with any tool available" and "Crap, I use Ubuntu for developing this crap piece of code that I produced and it is not working, please help" type of questions are on-topic for the site.
Still you see people that are asking for help around those 2 topics getting shushed and abusively being sent to other SE sites by users that have no authority for that.
No, this does not mean that every question posted that contains the word Ubuntu is on topic for the site, eg:
- How do I make Ubuntu logo shaped eggs
- How to I make a computer that can fly with Ubuntu
- Can Ubuntu cure cancer?
All of those would be closed for some reason or the other, namely: off-topic, unclear what you're asking and primarily opinion-based.
I recommend that you use some common sense and judging ability.
If you are new to the site refrain from posting "This should not be here, you should do X and Y" before you ask more experienced users, or even a moderator, for help and advise. And if you are an experienced user that detects that type of comments on questions instead of starting an opinion war just flag the comment for deletion, a moderator will take care of it.
Enough of those by a specific user and he can find another account to create because his will be blocked from commentingsuspended.
