Personal Fashion

OK, I guess it's pretty hackneyed to write about "how the Internet changes everything" in a blog. But I'm constantly reminded of how the power of a network decentralized things there were once controlled by a few. Of course blogs and the mass media are a perfect example, but here's another one: Neighborhoodies.
You can get a sweatshirt or t shirt with any freakin' message you want. From Park Slope to the Mission to "I am a pirate" and "Freakin' Cool." In the past you could find a silk screener to make you a custom shirt, but due to the lack of centralization and economies of scale it would have been expensive. Threadless is an even better example. Designers submit their designs electronically and shirts are made, creating an instant design competition and way to get unique t-shirts for $10. Anyway, in 2005 this is not that interesting to most people but I still marvel at it nonetheless.
