First of all: I love GIS SE! You have helped me countless times in the past. Thank you!
However, it has also been a source of frustration for me. As you can see at Are software installation questions on topic?, I had a installation-related question closed and reopened in the past. Today I submitted two more questions where a close vote is on the way (Installing PostGIS on older homebrew versions of PostgreSQL (e.g. email@example.com)? and Upgrading PostgreSQL with broken PostGIS installation ("$libdir/postgis-2.3" error)?).
I am fine if my questions are closed or moved to another site, but the current practice is not good IMHO. Installation-related are highly abundant and belong to the highest voted ones, but at the same time are sometimes closed right away.
From my perspective neither of these questions would have produced a meaningful answer on any other Stack Exchange site. Furthermore, I think software questions is the root of the whole Stack Exchange idea and it shouldn't be excluded in any of the topic-specific sites.
I feel like there are two strong movements in this community some in favor and some against software installation related questions. It would be great if we could agree on a common message in the scope section of the site and give moderators and people looking for help some clear guidelines.
