Some protocols have so much persistence, where others seem to be tied to one vendor's fate.

I wonder if its worth spending some time trying to understand what makes some protocols so robust and widely adopted. It's not just being open vs closed.

A few other examples:

  - PostScript (probably) / PDF (iffy)
  - CAN (adaptable)
  - G-code
  - Serial
  - HTTP
  - HTML (sort of, badly)
  - VNC (maybe)
  - JSON (for now)
