Lot's of buzz around bitcoin this weekend at Libertopia 2012 San Diego.
Trace Mayer gave an excellent talk and scolded registrants who paid their registration fee with credit cards at such an anti-state gathering. "Now you're really on the list" is basically what he said.
Good discussions on crypto-currencies with an excellent presentation on the potential of Open Transactions when stacked on top of bitcoin. If attendees hadn't heard about bitcoin before this weekend they sure did now. It's becoming very apparent to freedom-seekers that bitcoin solves many problems and I can sense a "tipping point" coming.
Jonathan Logan and Frank Braun also gave excellent presentations on Bitcoin, Agorism and Tradecraft. There was a great speech by Doug Casey as well (although he didn't mention bitcoin):
