Although if such a community already exists, then please give a link if you have one.
I would like to create a community where people can express their bad feelings or feelings in mini-stories and even get praise or support as an “Art Share🎨”, expressing their soul however they want, without stupid fan services and stuff, is it a good idea or not?
Induced demand also applies to social media. Having a dedicated community for something can cause people who had not thought to post something (because there was no dedicated community for it and they don’t want to risk putting it in a community where it doesn’t fit) to post.
Related, I really think we could use a /c/whatever community, for creative works and posts that don’t fit into any existing communities. It will also serve as a good place to assess when a community should be created, since you can just see what a lot of people are posting.
