To each his own. Long form on nostr includes support for better formatting of text and images so it flows better. The most popular clients all support displaying them now, so there’s really no reason not to use it.

corn how do I use it? I don't see a setting in Amethyst for it.
I use highlighter.com or habla.news to compose long form notes.
I believe Amethyst only supports viewing long form, not publishing. You can publish from a few apps. Habla.news, Yakihonne, Highlighter, Freerse are a few I know of.
