As a cypherpunk, when I first heard of bitcoin I was incredulous. But after many months of research and experimentation I became satisfied that the bitcoin protocols don't have any <i>obvious</i> flaws. God how I wish I could have saved some of that time with a nice summery video.<p>However, far more importantly then bitcoin I want to know why the hell we don't have proof of work as an email spam filter yet!!!!!!
