Writing such RFCs is dangerous due to the consensus nature of Bitcoin -
it makes people think the standard is the RFC, rather than the code.
I hear one of the better intros to Bitcoin is the Khan academy videos,
but I've never watched them myself. Once you understand how it works,
start reading source code - the Bitcoin codebase is actually really
simple and readable. However remember that the implications of that
codebase are anything but simple; there's lots of reasons to think
Satoshi himself didn't understand Bitcoin all that well, even by the
time he left the project.

I feel that I must respond to the statements that
1.
the Bitcoin codebase is actually really
simple and readable.
2.
However remember that the implications of that
codebase are anything but simple; there's lots of reasons to think
Satoshi himself didn't understand Bitcoin all that well, even by the
time he left the project.
On point one: if it was/is so readable, why hasn't it been documented better, if at all?
Why haven't the obscure names of important items been globally searched and replaced?
Why are there still mixed formatting "styles" still in the code. I think it is the fear that C++
is so brittle, that one change may bring the whole house of cards down.
I feel that it is the language (C++) that is hindering the expression of ideas in the code.
This goes to your point two about Satoshi's understanding. I think just the opposite:
that he knew what he wanted but that C++ hindered him in expressing and implementing it.
I think that if anything, C++ was what Satoshi "didn't understand all that well".
But then who does understand C++, really? See
https://groups.google.com/forum/#!msg/comp.lang.lisp/7xCvdzijzgU/4xCFzLc3d5EJ
and the quote:
Whenever I solve a difficult problem with C++, I feel like I’ve won a bar fight. — Michael Fogus
I don't think readability is attainable easily in C++. It requires intentionally writing so that
others may understand your code. How many programmers have ever done that? And this
is like swimming upstream in C++, where things are designed to be hidden!
