So far, I think the target is mostly for people inside the Hive ecosystem. I wouldn't be opposed to the idea of being able to share some of the things that I have for sale elsewhere, but but using it purely as a referral where you just share things you think are cool perhaps defeats the purpose of it being a feature that builds Hive.
I have very little experience with NFTs, so I can't really comment on whether it is an efficient way to sell digital goods.
I would like to see eventually the ability to accept payment perhaps in Bitcoin and one of the major stablecoins.
