   These were probably given as options and at the current market price rather than Jack's super low strike price. How do you make something valuable? Convince others it has value, and do it with only 20% of your stake.

    I agree with your point that you don't read about the "silent majority" on Hacker News and TechCrunch. Consumer internet touches more people's lives so you hear about it more, especially when said founders are 22 and str
