We have various platforms, such as discourse. We also have the Haskell survey.
But I still feel these mostly represent hardcore Haskell users.
How do e.g. tooling maintainers reach out to their industrial downstream users? How would CLC or GHC SC do that or even library maintainers?
I think some of us have a feeling of the industry pulse, simply because they have accumulated friends and colleagues from different places in industry. But that might still be a biased view, depending on ones career and exposure.
