Michael Linton’s talking about community currencies – tribes (regional, social, etc.) building their own currencies and trading them along with the standard federal currencies. He’s helped lead a very long and cumbersome software system for managing these currencies.
This is a fascinating topic and Michael seems to be an expert in it, but it’s not a fascinating presentation – it’s just weaving (or, uncharitably, rambling) around, the why took a long time to explain, and unfortunately his speaking style and crowded powerpoint (his first time using PPT) doesn’t work well in long-length presentation format. Some people are engaged but there’s a significant amount of browsing/blogging/twittering about.
