Very useful, thanks! Q: is there a place where a non-specialist could post a one-pager saying "Here's an idea, possibly interesting, that doesn't seem to exist in current literature", such that professionals might take a quick look? PhilPapers? Maybe useful, despite problem of filtering out junk?

Thanks. PhilPapers indexes existing published papers, but Bluesky is probably as good a place as any to do this. Some time ago on Twitter, people were using the #philq (philosophy question) tag to do this. Perhaps we should reinstate it! 😊
