What makes something a digital garden?

In 2025, I think a digital garden has three primary features:

• It's on a computer
  • For me this follows not just from the word "digital", but from the aesthetics of "digital gardening" as a verb phrase
    • a collection of digital assets invites one to perform a certain kind of sophisticated bookkeeping
    • digital assets
• It's hyperlinked
  • There is an addressing system for each note or page
  • The addresses are used inside the note body
  • sometimes directly inside the text as a way of "inlining" the content of one note inside another
• It is "living"
  • it can implicitly always be rewritten.
