We are developing Bitcoin as, how we call it, 'alternative local currency with global reach' here in Berlin / Kreuzberg.
I will inform about these developments in my talk at the conference this saturday morning (10:30am, 'cheese knives versus secular money'). Come around and contact me there in case you are trying the same somewhere else or are thinking about it so we can share ideas and experiences.
Other than that let us use this thread to get this exchange of experience started.
I have been running a brick and mortar business (ROOM77, bar and restaurant in Berlin) accepting BTC for a year and a half now and that _does_ have an impact on the surrounding environment, individuals as well as businesses.
So see you on the weekend or talk to you here next week!
Joe
I'll be glad to hear more about it!
