I know there are several out there for casual conversation and while that does work for what I have to say a lot sometimes I just want to vent and put something out there not expecting a response.
Also is there a better community for inquiring about find other communities? I have been using various community finding sites but searching for the term “rant” in them was just getting me miscellaneous results like fitness and vegan communities.
Create the community yourself and disable replies.
I agree with another commenter, though. What’s the point of publishing a rant here without expecting comments?
Or you just want to be read?
A journal or a blog would be more suitable.
