At this point the only way for PGP or really any user-based encryption to get widespread use, gmail, yahoo and microsoft need to adopt it and integrate it into their webmail client, possibly as a semi-mandatory feature that's opt-out instead of opt-in. Anything less will fail as no one is interested in getting a new email address. Anecdotally, I've tried three of four times to learn how to use PGP and integrate it into my workflow and failed each time, so it definitely needs work (at least if they want me on board :))
