This question already has an answer here:
- How can I propose a new site? 1 answer
PPS. I have added a related question now - How to proceed when proposal for a new Stack Exchange is turned due to admin's ignorance of domain? which addresses the point raised here.
PS. The reason not to close can found at the end
Some years ago I proposed a new StackExchange for non-Ubuntu desktop environments because
Ask Ubuntu did not like questions on Debian
There are whole areas of Linux which are not Ubuntu specific
Unix SE tends to be focused more on lower level, glue level aspects of Linux and the command line and it doesn't go into desktop issues as much.
bash 14758 grub 6639 swap 5937 init 5076 mysql 3618 init.d 2845 crontab 2626 systemd 2090 docker 1873 zsh 1460 system v 1451 python 1333 upstart 877 rc.d 922 puppet 502
debian 9389 arch 7574 ubuntu 7510 mint 6290 fedora 3009 gnome 1552 kde 986 kde4 322 kde5 186
You can see from the tags how much Unix/Linux is focused more on the underlying glue and utilities rather than issues relating to the desktop environment. Combining the two areas is like trying to serve Windows server administrators and Windows end users from the same forum. I don't think any SE developers and administrators would ever do that
In Linux server administrator issues are quite different from desktop user related issues, but as most Linux desktop users have to be their own administrators, there is an overlap but only the minimum desktop users need to do to fix the desktop issues and get back to work.
To be honest each of the Linux desktop derivatives need their own SE and admins can probably tag them and move them if they are miscategorized or are in the wrong forum.
I brought this up some years ago and it was shot down immediately on the grounds that Unix and Linux SE is a good substitute. You only have to look at
r/linux on reddit to see how conceptually differently they are viewed.
Whatever the case may or may not be for different Stack Exchanges for the desktop environments the desktop environments and the OS proper should have different exchanges. Linux itself is the operating system, the kernel more accurately and the derived OSs and desktop environments are quite different.
UPDATE For those who believe I should make a new proposal this is question explains the reason why. Is there any trace of my closed proposal?.
If there is a means of getting past a proposal which will allow other interested users to chime in before it is immediately turned down or there is some other faq, question or Q&A on how this point can be discussed I'd like to be directed to it
