Not sure why it is the banks responsibility. If they sold their home, paid off any outstanding mortgage they are free to do what they want with the remaining money. However it still doesn't mean it was a good idea. What they have failed to see is that other social media companies usually burn other peoples money, and those other people generally are not going to become homeless if their gamble doesn't pay off.
I am hoping that the "we sold our house and cars and everything else" is just some BS to get themselves some publicity because I dont see how their costs are so high that they need to spend so much money on it. With their low numbers they are hardly going to be paying massive sums for hosting their site.
