📚Social Media platform only about BOOKS-Copper (and a Q about community)

Has anyone looked into COPPER ?

UPDATE:
It seems like it was a great idea—but for some reason it just fizzled away. The startup lady still has an active Instagram, but the company folded (nothing new for 2 years).

ABOUT COMMUNITY:
I have a little community “set up” for my readers but it also seems no one is interested in meeting there. Has anyone had success? As for me, I’m focusing on regular communication via my email list.

As for a community, besides talking about the books with the author, I can’t think of a “premium experience” that an online community would create. Regular meetings and giveaways—I’ve had live meetups and launch parties. But it seems to be spinning an unnecessary plate. Readers just want books. Write your book. (Maybe that’s what they found out with Copper; otherwise I’m pretty much off social, except for here.)
