SV mentality.
Dwolla is too good for my 75k? Good for them. Companies like BofA, Walmart, GE, and literally thousands of other companies would love to take that money and put it to use. Only in the upside down world of SV would you have to be somebody to have your investment accepted.
As far as the prediction market, it would be useless with play money. Skin in the game is what drives efficiency.
