Life on the edge
The geek-driven world of new "decentralized" technologies like Wi-Fi, blogging and Web services is more about cutting out the middleman than finding a business model. The technology industry has long been shaped by the creative tension between technologists and businesspeople, otherwise known as geeks and suits. Geeks make new stuff primarily because it's fun, because it's useful, and because they can. Suits make new stuff primarily because they hope to earn a profit. Yes, that is an oversimplification, and there's overlap between the two types -- there are plenty of profit-seeking geeks and geeky business folks. Still, the distinction is real.
