Expanding boundaries

I would like to expand my universe here on Hive, as I am familiar to some very good communities like Sportstalk.social, Weedcash.network, Palnet, Proofofbrain, ... and Leofinance of course. But this week I saw some unusual tags, of which I had no idea what they meant. So I am curious about other communities that exist, what their added value or niche is, and maybe I could add some extra value and content to that.
So feel free to promote your community or tribe to me, and drop it in the comments and tell me why I should be joining that particular community.

I am looking forward to it!

Sincerely,
