Ka is future-proof

Notes taken with Ka at hand tend to be future-proof. Because, at minium, your plain-text notes are expected to satisfy only these two properties:

  1. Markdown format
  2. Linked to one another (regular links or Wiki-links)

These two things can be done for a lifetime. Everything else (including Plugins) may come and go; but the underlying plain-text data will remain for eternity.
