"Everything about web architecture; HTTP, HTML, CSS, is designed to serve and render content, but most importantly the web is formed where all of that content is linked together. That is what makes it amazing, and that is what defines it. This purpose and killer application of the web is not even comparable to the application frameworks of any particular operating system.
That’s the kicker. We talk about ‘web applications’, the ‘open web stack’. People are citing HP’s purchase of Palm and investment in WebOS as a victory for the web. We talk about applications built using HTML, CSS and JavaScript in the same breath as content published using HTML semantics.
Want to know if your ‘HTML application’ is part of the web? Link me into it. Not just link me to it; link me into it. Not just to the black-box frontpage. Link me to a piece of content. Show me that it can be crawled, show me that we can draw strands of silk between the resources presented in your app. That is the web: The beautiful interconnection of navigable content. If your website locks content away in a container, outside the reach of hyperlinks, you’re not building any kind of ‘web’ app. You’re doing something else."
