I'm not ignoring it and most of the world has been using crypto for
online stuff since SSLv2 was released to the world.

I'm sorry to say it but a lot of the users have been here for a while -
most people that use crypto just don't know they're doing it.
Ironically, if users don't get good advice, they'll just be in the same
spot - thinking they're safe when they're not - all over again!

I think that the real changes belong in the platforms - anything that
requires configuration is probably already doomed to fail and screw a
user. That's generally the approach that I've seen work - everything
that requires 0) user education and 1) realistic honesty about threats
or risks results in 2) denial or mistakes or a bork'ed tool shooting the
user in the foot.

Since clearly a few loud people were bent out of shape by my comments -
they have no idea that I encouraged you or tried to help out; so let me
set the record straight: go you!

I think it is *great* to make the book and I think it is great to do it
with a set of unifying principles - it will help to ensure that good
stuff gets into the book and crappy stuff stays out of the book or is so
noted as crappy or contentious. I think that means that peer review is
essential before rushing to publish.

I really encourage you to put in a few chapters about the following:

 social and technical compartmentalization
 targeted exploitation realities (from Core Impact to Metasploit)
 threat modeling
 intention/goal based risk analysis
 physical security risks
 practical information on real surveillance/censorship systems
 getting involved
   going from a user (to a translator or...) to a developer
 outlining the currently missing tools that we need to build

Overall - I think the EFF's SSD is a great document to consider in the
process and I think you're well aware of it...

All the best,
Jacob
