HTML Imports: #include for the web

> An import link doesn't mean "#include the content here". It means "parser, go off an fetch this document so I can use it later".

This is an important point. "#include for the web" would just be a client-side version of Server Side Includes. This is actually letting you link to snippets of HTML the same way you do with images, scripts, stylesheets, and so on -- meaning they can also be manipulated with Javascript.
