The New New Economy: More Startups, Fewer Giants, Infinite Opportunity [del.icio.us]

What we have discovered over the past nine months are growing diseconomies of scale. Bigger firms are harder to run on cash flow alone, so they need more debt (oops!). Bigger companies have to place bigger bets but have less and less control over distribution and competition in an increasingly diverse marketplace. Those bets get riskier and the payoffs lower. And as Wall Street firms are learning, bigger companies are going to get more regulated, limiting their flexibility. The stars of finance are fleeing for smaller firms; it's the only place they can imagine getting anything interesting done.
