Abstraction != Difficult.  Please understand that the principle in play 
re. AWWW is "deceptively simple" which is a function of good 
abstraction. URI abstraction is a fine example of said principle. This 
is what makes the Web work.

For WebID based authentication to work it doesn't need to compromise the 
virtues of URIs. Just use simple examples to make matters clearer.

The solution to the problem is that you don't introduce technology via a 
technical spec. It's conventionally achieved as follows:

1. conceptual guide and overview
2. technical specs
3. implementation guides and examples -- this is where you can be 
specific about URLs, Turtle docs etc.. by using them in all the examples.

When you start from #2 you are vulnerable to:

1. political distractions -- e.g., format (as opposed to semantics) 
oriented warfare
2. FUD -- when the abstract nature isn't obvious those threatened will 
come at you with FUD.

We don't need to compromise the essence of the Web for all of this to work.

Remember, HTML wasn't prescribed to the world en route to WWW bootstrap, 
the "view source" pattern from early browsers enabled folks to cut and 
paste what was behind the page (which could have been anything) into new 
spaces en route to understanding the implications of fusing Hypertext 
and TCP/IP.

Standards are retrsopective things, they are the result of coalescing 
around what works, so the sequence is always:

1. de facto standard -- common practice
3. industry standard -- accepted best practice.
