Notes are not articles
The audiences differ: I write my notes for myself, but I write articles for others to read.
While notes have fairly free-form content, articles are more structured. They open with a lead paragraph and often have a table of contents.
Notes are atomic and often address only one idea, while articles connect multiple ideas together in longer-form writing.
To figure out: Articles can go into a feed, which will be chronological. How does that rhyme with my thinking that Short-form content doesn’t need to be written as a chronological sequence of blog posts?
