I think this is a great idea; makes you think why blogging isn't as easy as taking notes on Apple Notes.

Between the recent launch of Obsidian and this, I'm probably going to go with Obsidian particularly because: I know how to set up websites and I always trust offline more than online (I've lost multiple drafts on Substack which has taught me always to either use GDocs/Dropbox Paper/Offline text).
