Ask HN: What's the best way to talk to an expert directly for advice?
For example, if I wanted to ask questions on a certain path I'm taking to learn ML or get advice on how to approach a certain problem Reddit is great. r/MachineLearning and r/MLQuestions are decently active, as is Cross Validated, Stack Overflow's stats site. You could also email me- email's in profile, I'm happy to chat. I currently work in ML as a consultant.
