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 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.
