Same with world-wide-web. Conclusion? You don't need to understand specific technology, you can just use it.

Yep, it will need to get real pretty and easy to get to be used by the average Joe.
I think that with the obsession with design nowadays it will happen much sooner than with email.
(People really do not know how to use email, most of my friends/family just keep all their messages in the inbox, FOREVER...)
