I'd love for them to make a Leanpub version (PDF + EPUB + MOBI). I've tweeted at Blake asking him if he's interested, and obviously anything that is made should be done with Peter Thiel's approval.
It would have taken us 5 minutes to make a Leanpub version, but we respect copyright, both Blake's and Peter's, so we haven't :)
Anyway, Blake, please email me (peter@leanpub.com) or tweet me (@peterarmstrong) if you're interested...
