I sometimes hear that someone doesn’t want to post an idea because they feel like they would have to write a whole post, and it would need to be long, complex, and fully fleshed out.
I think short and simple Forum posts are fine — in fact, it’s often better for a post to be significantly shorter. (You could also consider making it a Quick take.)
Would it help if there were some kind of commonly understood shorthand way of saying “I am writing this post in a shortened format and thus recognize there are many missing caveats and examples, but I may continue to expand on it in future updates and if you would like for me to address or clarify anything feel free to leave a comment on that… [etc. etc.]” At the very least, there have been times where I have wished that I could say a disclaimer like that. Of course, someone can just say all of that, or that might just say things like “take this with a grain of salt” (although that phrase doesn’t convey the full message/meaning).
I like that post a lot! The people I tend to share early stages ideas are ones that try to make it better / understand it more or something.
