Thanks for posting this @lkessler! The top rated meta post discussing their closure included this interesting opinion:
Virtually every new question that is asked is eventually put on hold
and then rejected, based on the site rules. That implies to me that we
aren't giving the community what they want. The community is the one
that asks the questions. The community wants web site reviews, product
idea reviews, and all the things our rules say we can't offer. We can
either give the community what it wants, or fade away.
I feel that this was a large factor in the Library Stack Exchange failure also. I tried to engage with that community and was astounded by the heavy-handedness of the mods. Their narrow concept of what Library Stack Exchange should be did not seem to match the diversity and breadth of what the international library community wanted. I watched them chase away many SE newbies (experts in their fields) that had asked sound questions to real problems. I tried to edit and improve some of the questions, but was chastised for it. After that, I too left. And I AM a librarian :/ pfft
Glad that we seem to have a community that is willing to work to improve questions to ease them into the SE model.
