I have a question, but it may not fit best on Software Engineering. Where else can I ask it? lists a number of Stack Exchange sites that are related to software development, some more closely than others. However, none of them accept overly subjective questions. Subjective questions in general just aren't a good fit for the Stack Exchange format.
There are other communities of software developers out there. Reddit has several subreddits related to programming, computer science, software engineering, and IT, but you'll need to check each community's rules for what to post. Dev.to is a pretty robust community, too. There may be others, too.
