I wonder what would happen if we started taking smart ideas that didn't gain traction in the U.S. due to cultural and regional differences and then trying them overseas (e.g. the reverse Samovar brother) I guess the really hard part would be isolating a startups failure or lack of popularity to culture or density. At least enough to spend time and effort to get a similar thing going in another country only to face not that much better odds of failure.
