OK, I took the liberty of sending an email to Lew directly the following is what I sent;

Hello Lew,

Just a quick note to inform you of an author that recently presented his new book on Cyrptocurrency in Vienna.
I am not affiliated with the author in any way, other than we share a common interest of Austrian Economics and
limited/decentralized government.

If you get the time please check it out and consider it noteworthy for inclusion on your site.

I mentioned to the author in the comment section of his post that he should contact you directly.
