Too many to choose from :) As a reader and writer, I value Hive Book Club & Blockchain Poets & Threespeak (where I post poetry readings).
But, I also love food, nature, photography and travel, so: Foodies Beehive, Amazing Nature, Photography Lovers & Hive Crossculture.
Lastly, this morning I discovered The Minimalist, which I instantly loved and found inspiring, since I'm trying to simplify my life, declutter & practice detachment from needless things.
I hope that you might discover a community or two, through ones I mention, above :)
