The way a startup makes money is to offer people better technology than they have now.
And that's kind of exciting, when you think about it, because all three are doable. And since a startup that succeeds ordinarily makes its founders rich, that implies getting rich is doable too. If there is one message I'd like to get across about startups, that's it.And while they probably have bigger ambitions now, this alone brings them a billion dollars a year.There are plenty of other areas that are just as backward as search was before Google.I can think of several heuristics for generating ideas for startups, but most reduce to this: look at something people are trying to do, and figure out how to do it in a way that doesn't suck.For example, dating sites currently suck far worse than search did before Google. They seem to have approached the problem by thinking about how to do database matches instead of how dating works in the real world.
