Why could not a forum like this one be a hidden web service, wherein one 
logs in with a zero knowledge password protocol.

The client could be written so that the user interaction remained the 
same as at present, even though the underlying protocol would be very 
different.

Your client, whereby you interact with the forum, has a master password, 
and typically concocts per forum passwords on the fly, which is to say 
per mailing list passwords on the fly.

Usernames would have the form example$forum_name

Forum name would be non memorable, but the user would not typically need 
to type it, or even see it, merely click on it.  (Zooko's triangle)

Messages sent to the entire mailing list would default to public, that 
anyone could browse without necessarily creating a username and 
password, but more private non default forums would be possible - for 
example, that even messages sent to the entire mailing list default to 
private, and that in order to sign up, you need to send a request to the 
list that no existing member of the list blackballs.
