I never had a problem with a post closed on reddit and was able to ask very open ended questions, so independently of the rules, it was possible for me to get the help i needed, which wasn't possible on stackoverflow
This isn't so much about the first person asking the question-
(if they were really the first and not just failing to find previous occurrences of the same question being asked - because of the popularity of Reddit and how it works, the netiquette rule of searching first and avoiding duplicates seem to be forgotten in other spaces)
-but about those coming later with similar questions.
