I attended
http://AgoraFest.com this past weekend (near Red Wing, MN) and Bitcoin was well represented (two sessions on Bitcoin, as well as Bitcoin coming up at least once in a most every other session or conversation).
Silver was being accepted as well. I had some silver dimes with me and used them to pay for dinner and later drinks. That as the first time I had ever used junk silver in trade (rather than simply buying or selling a precious metal for investment purposes).
What was interesting was that even these little silver dimes were not of fine enough granularity.
For instance, in paying for a beer. One silver dime was too little. Two silver dimes was a little high.
If the merchant accepted DYM (a silver dime-backed voucher issued through Ripple), I could have paid with the precise amount (e.g. 1.6419 DYM).
I think that Ripple (and DYM) is something with great potential.
Anyways, I'll still be in the Twin Cities this week Wednesday so will be at the meetup at Club Jager.
