I asked a question about the difference that processor architectures make to compiler performance. I asked with a lot of supporting detail to make it possible for someone who knew facts to be able to say X feature of the processor directly helps compilation and I tried to avoid simple comparative "opinion-based" wording.
Still, it was closed.
We seem to have an increasing tendency to close questions as "opinion based" when I see many of them as being more, the closer doesn't know enough about the topic to know if there will be relevant facts so assumes the question leads to just opinions. Is this just "moderation activity for ego sake?"
(Yes I looked at the profile of the person who closed it and they don't seem to be an authority in this area.)
It was a real issue I was trying to get answered and I put significant work into technical preparation to seed the answers. The question just won me a silver badge for the 2,5000 views it's had so I was just reminded of how annoyed I was by the closure.
