As a maintainer I feel like the first tip is not the best approach sometimes. People tend to raise a lot of “I got a problem” issues (well, we all do sometimes) which they solve themselves in a short time (e.g. a misconfiguration). Responding instantly to such sounds inefficient.
Fair point! Rapid response is definitely valuable for thoughtful issues or PRs. For "questions" we try to just ask for more clarifying details or do a brief pointer to documentation. I find it can also be useful to deliberately slow down responses when getting caught in a low value conversation - kinda like rate limiting undesirable traffic to your website <grin>.
