Deve essere linkabile
Deve permettere l’accesso a qualsiasi client

Con enfasi sulla seconda:

Links aren’t the complicated part; it’s the part where your thing should allow any client to access it. For the web, that rule is pretty clear: whether you use Chrome or Safari or Edge or Opera or whatever, when you click a link or type in a URL, you get the page you wanted (more or less). Those pages are agnostic to the client. […]

When people talk about the “open web,” agnosticism to the client is really at the heart of it.
