When I have questions that I don't really expect Google to have answers for, I use IRC. Mostly about second opinions, in depth technical stuff, or when I don't have time to create a question on stack overflow because Google can't always find the lexical context between my Google search and the actual solution. Chat is also much better than forums when you want to interact. Slack and discord are bloated software, which are centralized. IRC is much more lightweight and simple, and most of the time logs are available. It's more open.
