I don't know if you've seen them, but since no one else has mentioned them, there's a few other communities that might work for posting your thoughts besides casualconversation:
- !showerthoughts@lemmy.world (tends to be shorter form, perhaps more absurd or sillier in tone than you want. Alternate option at !ShowerThoughts@sh.itjust.works)
- !justpost@lemmy.world (mostly memes/links but occasionally someone does a text post)
- !goodoffmychest@lemmy.world (other posts might be less neutral than you're looking for but your post doesn't have to be a rant or vent or w/e)
- !general@lemmy.world
In one of your other comments on this post you mentioned somewhere to ask fact oriented questions rather than open ended questions as encouraged by asklemmy. For those, you might consider:
- !nostupidquestions@lemmy.world (some people might suggest just using google/search-engine-of-your-choice, ignore/block them if they're jerks about it. Alternate option at !nostupidquestions@lemmy.ca)
- !askscience@lemmy.world if it's science related
Otherwise just post your question in a community appropriate to the topic. Hope you find what you're looking for from Lemmy.
