If banksimple.com is not a bank, what is it?
I don't see how this concept takes off. First and foremost, BankSimple is NOT a bank but a tech company masquerading as one. BankSimple leaves industry regulation and treasury management -- the CORE of banking, to outside parties.  Call me old fashioned, but I prefer to have as few stops between me and my money as possible. If not for a fear of losing it in a robbery and inability to earn interest, I'd shove it under a mattress. So why would I want to bank with an intermediary, who admittently doesn't understand how the process works? How is that "looking out for my interests"? And how is your security better than other institutions that offer 128-bit encryption and multiple security questions to test a customer's identity?  I'd like to add that not charging overdraft fees and providing lines of credit to help customers out in the event they spend more than they have is nice in concept, but what happens when those same customers do not make deposits to cover their shortfalls? When it comes to money, people will take advantage of any opportunities they have to circumvent the system. Especially if funds are tight.
