I really apreciate this follow-up post. Now it's clearer why proof of brain's token is higher valued than other HIVE tokens. I personally like the enviroment, it's less intrusive and it's easier for me as a creator to write my own topics, intead of having to join challenges just to earn.
I also wish proof of brain had a mechanism for evergreen content to earn years from now, not just the first 7 days.
Cheers! :D
