I went to a friend's wedding tonight and introduced bitcoin to 6 people. Here are some stats:
1) Three people (half) seemed not to be very interested. These people ask questions like "what's the point?" They are consumers, and are not interested in bitcoin because they can't buy anything with it that they can't buy with dollars. They are not investors or entrepreneurs.
2) The other three new people seemed pretty interested and told me they plan to Google it.
3) Of the interested people, one seemed particularly interested and twice said he plans to buy some.
4) No one I talked to had already heard of bitcoin except people I had already told about it. And these are people that are not technically illiterate. So bitcoin is pretty far from mainstream yet.
