The company my friend works for has a slack channel for help with code, like an internal stackoverflow. It’s almost inactive now.

I noticed the same thing. Another thing that seems to have disappear: lunch and learn focusing on the tech stack. And I mean specifically about "how to do this in <programming language", not product/company focused.
