(Not to single you out, but this is a good entry point.)
So somewhere between this and the =93every user should have their own =

usability gap.
- =93I just bought something from this boutique website, how do I (or my =

- =93My friend gave his buddy my email address to send a resume for that =
job opening I have. How do I permit him to send me email?=94
- =93This .gov entity needs to email me about my (taxes|health care|car =

- =93My long lost high school friend found my email address somewhere =
(and isn=92t using gmail, hotmail, yahoo, =85.), how do I keep her from =
getting blocked?=94
All of these end-user questions will have to be answered by any such =

you describe here. And if you=92re going to say the solution is =93in =
