What do you do now, if you don't mind me asking?
Abstracted a little, capital markets start-ups. You could add value by hybridising Silicon Valley and New York.
Go any further, e.g. to a Pinterest, and I don't know. Maybe there is a business development role? I'd guess you'd be throwing away a lot of your existing value at that point.
Call people. Most are very willing to help.
The chemists and high school teachers turned ninja hax0r can't be far off. Someone please warn me so I can short XLK.
However IPO's with unreasonable valuations, and investments greater than what's needed is a pretty good sign of bubble. So i'll let linkedin, and facebook make me scared of a bubble. Not to mention the startup Color.
