I don't think this addresses jkaufman's comment. He asked:
Why aren't these people using the sites that already exist?
These sites already existed when your friends were applying to college. So if they say "I wish this existed when I was applying to college", the key question to answer is why didn't they use any of the competing sites, which did exist when they were applying to college? Your response that "these people looked through your own website's questions" does not address this question.
(As an aside, I would humbly suggest that you read through jkaufman's -- and a few other people's -- advice somewhat more carefully, as your responses indicate that you've misunderstood some of the key points, see also my earlier explanation of a premortem, which had already been explained to you once earlier in the thread.)
My motivation behind this post stems from Aumann's agreement theorem. It seems that my opinions on startups differ from most of the rationality community, so I want to share my thoughts, and hear your thoughts, so we could reach a better conclusion.
I think that if you're smart and hard working, there's a pretty good chance that you achieve financial independence within a decade of the beginning of your journey to start a startup. And that's my conservative estimate.
"Achieve financial independence" only scratches the surface of the benefits of succeeding with a startup. If you're an altruist, you'll get to help a lot of other people too. And making millions of dollars will also allow you the leverage you need to make riskier investments with much higher expected values, allowing you to grow your money quickly so you could do more good.
A lot of this is predicated on my belief that you have a good chance at succeeding if you're smart and hardworking, so let me explain why I think this.
Along the lines of reductionism, "success with a startup" is an outcome (I guess we could define success as a $5-10M exit in under 10 years). And outcomes consist of their components. My argument consists of breaking the main outcome into it's components, and then arguing that the components are all likely enough for the main outcome to be likely.
I think that the 4 components are:
The Idea
Your idea has to be for a product or service (I'll just say product to keep things simple) that creates demand, and can be met profitably. In other words, make something people want (this article spells it out pretty well).
What could go wrong?
