It's been really interesting reading everyone's uses of bitcoin, though I still feel that most of them are for the novelty of buying with bitcoin versus it being substantially more cost effective.

For the people buying things at physical locations in Berlin, why has bitcoin caught on so much there? Seems there must be an economic reason behind it more than just a large bitcoin-favoring libertarian community.

I'm curious if anyone has seen any big "legitimate" uses for which bitcoin has a clear advantage over standard fiat money. I've been dabbling in bitcoin for a little while now and would love to see it grow, but as I talk to people about it, it's been hard to see how it will find a mainstream use in a developed country. I'm really wondering about this more from a transactional perspective as opposed to using it as a hedge against inflation, etc.
