Have a look at !newcommunities@lemmy.world . Sort by top if needed and especially this post

Edit: and I also learned about !wowthislemmyexists@lemmy.ca

I used to sub to new subreddit via such subreddits, or in comments of posts that showed me through a discussion. Or sidebar of subreddit on related ones.

No. I am very happy at discovering a new place. I also miss the social media, pre 2010s. like in 2005, it was amazing and people felt much closer. One had a feeling that everyone is genuinely here to help and enjoy while socializing, rather than karma farming.

I am talking before Facebook grew big. The time of Orkut, Gazzag, old reddit, Slashdot. or even yahoo messenger, mIRC, before all those websites became a thing. I was not afraid of posting something, and wasn’t looking for votes, or afraid of down votes. Main aim of contributing to a post of joining in the discussion.

I wish someone or a dev could make this list in these website and propose lemmy/kbin equivalents for us the redditors to join instead. On the other hands mods of those subreddits if they want they can make a community over these platforms.
