Couple reasons:
1. Long form nostr is super painful. Half the time drafts break, and the formatting is a nightmare. While medium is retarded, at least I can literally copy / paste direct (whether from Substack or Docs), and all the formatting comes along.
I’ve told this to Pablo and others many times. Nothing’s been built to address it.
2. Even if I did publish in Nostr - which I generally do when I finally have the time to do all the formatting - I’d still generally post on shitty medium simply because it reaches a different group of people.
Interesting. Copy and paste works for me on highlighter. Picture formatting isn’t as good though.
