He spoke at the bitcoin conference in Prague (mainly about himself and his crowd-funding-site piratemyfilm.com, which uses bitcoin for funding movie- and other projects). He has mentioned bitcoin as the "currency of the resistance" in his "Keiser Report" in april or may 2011 and interviewed Rick Falkvinge about Bitcoin very early (also in Keiser Report).

He has clearly promoted bitcoin and still said he would be "using his media leverage to help tony (bitpay) reach the goal of 1 million new bitcoin users in 2012" (I'm assuming this will fail, but nevertheless, he's a bitcoiner of sorts and one that reaches quite an audience.

Should we care if he denounces libertarians? I'm not sure... will watch the vid now.
