Awesome, welcome!! Glad to have you join the community, and you are right.. it really is a bit of hidden gem.

Communities are a bit hard to break into as some of the "chat" happens offchain, in an app called discord.

But, if you havent, feel free to check out Steempeak.com "tribes" as well as the beta communities site https://beta.steemit.com/ to be able to search some of them.

The beta is just a live test version of the upcoming community features. You may have an easier time finding content you like and the people who write it etc.

If you are on discord, or want to join it.. I will gladly get you in touch with a few that way too.. but honestly I think with these new features less and less of that will be happening on discord.

Feel free to ask any questions you have.
