"Noticeably absent from the Reads feed, though, is the ability to compose an article of your own. This is another understandable design choice for a mobile client. Composing a long-form note on a smart-phone screen is not a good time. Better to be done on a larger screen, in a client with a full-featured text editor.
Tapping an article will open up an attractive reading interface, with the ability to bookmark for later. These bookmarks are a separate list from your short-form note bookmarks so you don't have to scroll through a bunch of notes you bookmarked to find the article you told yourself you would read later and it's already been three weeks.
While you can comment on the article or zap it, you will notice that you cannot repost or quote-post it. It's not that you can't do so on Nostr. You absolutely can in other clients. In fact, you can do so on Primal's web client, too. However, Primal on Android does not handle rendering long-form note previews in the Home feed, so they have simply left out the option to share them there. See below for an example of a quote-post of a long-form note in the Primal web client vs the Android client."
