I really like the idea of indicating epistemic status for posts. The closest to that for code might be version numbers where anything under v1.0 should be taken with a grain of salt. This dynamic of spitballing-or-serious appears on HN sometimes when a personal project gets shared by a third party, is good enough to attract serious comments/critiques, but then the author of the project chimes in to say “I totally didn’t expect this to be shared here it’s definitely a work in progress…”
