Speaking of investing, now that your startup's been acquired have you thought about becoming an angel investor?
Everyone's always saying there's a need for more startup investors who were formerly startup founders themselves. Checking your profile on Fleaflicker, I see you're in NYC; there are bound to be angel investor groups that you could join if you didn't want to do it alone.
I would not invest in founders that aren't passionate about what they are doing.
