No I've not seen anyone give that a go. I figure it makes sense. Text files aren't large even for full manuscripts. I suppose you could create them in multiple file formats too. It's something I've been pondering for a while but i don't know enough about the limitations of NFTs to be sure.
Yeah the first time rights issue I've seen be a problem for other people. I always figured I'd go the self publish route and try to market my work myself.
It's a real shame that hive won't be the place I publish though, I still love this place.
Though if peakd placed adds on my work and paid me advertiser revenue... That might change.
