That's fair enough. Again, honestly? I'd say still stick it in the bank and start a web-based business around an app you write. Its extremely cheap to take this route.
Bootstrapping is an incredible rush and it makes you think about what is absolutely necessary in your business, then cut that in half.
It's one of those "living on the edge" kinda feelings, the payoff is worth it.
If I was in your position, that's what I'd do.... but take my advice as much as you can take the advice of any random stranger on the net telling you how to invest your money... with a grain of salt.
