I think most people would agree with the sentiment, but it's probably a side effect of people being a bit lost.

If you can't find the community or discussion where you could contribute more niche information, having the general reddit exodus topic at least lets you participate.

And I think that is the common thread of optimism. Even with the confusion and the jank, it still feels good to be somewhere welcoming and new.

Yep, it's definitely gonna take some time to adjust.

I've setup my own community as I couldn't find one that existed for it already, but no idea how best to actually spread the word about it.

But enjoying finding out how it all works and discovering more communities

Same. I'll just do it here though: !outside_rpg
There's a community to promote your new communities in, it's called New Communities (funnily enough) on lemmy.world. I'm really new to this but I'll try to link it
New Communities - LemmyWorld

A place to post new communities all over Lemmy for discovery and promotion. # Rules The rules may be more established as time goes on, but it’s important to have a foundation to work on. 1. Follow the rules of Lemmy.world - These rules are the same as Mastodon.world’s rules, which can be found here [https://mastodon.world/about]. 2. Include a community title and description in your post title. - A following example of this would be New Communities - A place to post new communities all over Lemmy for discovery and promotion. 3. Follow the formatting. - The formatting as included below is important for people getting universal links across Lemmy as easily as possible. # Formatting Please include this following format in your post: [link text](/c/[email protected]) This provides a link that should work across instances, but in some cases it won’t You should also include either: [email protected] [/c/[email protected]] or instance.com/c/community [http://instance.com/c/community] # FAQ: Q: Why do I get a 404? A: At least one user in an instance needs to search for a community before it gets fetched. Searching for the community will bring it into the instance and it will fetch a few of the most recent posts without comments. If a user is subscribed to a community, then all of the future posts and interactions are now in-sync. Q: When I try to create a post, the circle just spins forever. Why is that? A: This is a current known issue with large communities. Sometimes it does get posted, but just continues spinning, but sometimes it doesn’t get posted and continues spinning. If it doesn’t actually get posted, the best thing to do is try later. However, only some people seem to be having this problem at the moment.

I think there is a good chance at the moment that people will find you. Without much map of where to go I have been searching for community names that include my interests, and I suspect other people are doing the same given the community I started has been getting subscribers and I haven't told anyone about it!
