via Boingboing: On Mindjack, Joshua Ellis writes at length about what he calls Taste Tribes, friendship by cultural affinity--liking people who like the same stuff. Blogs are the engines for the smarter artist/chiefs of their own taste tribes.
I cooked something up along those lines in 1999 at Shagpad, which was based on the Austin Powerish, Abercrombie & Fitchy theory that people bought stuff in direct relation to its ability to get them laid. Or as the VC-Powerpoint presentation-ready slogan goes, "Shagpad.com leverages web and e-commerce technology to monetize aspirational lifestyle portfolios that facilitate getting mad play." The idea came out of some client work which became, in part, Pop.com (They chose the wrong part, I thought.) At Shagpad are a couple of essays that are not quite embarassing enough to take offline (and besides, the buy-this-lifestyle Amazon links usually pay the hosting).
[Update: It should be noted that I peeled off my friend Jeff's last name; he's a sculptor in Red Hook, and the Google searches were beginning to cramp his style. Now that Wallpaper* has declared Red Hook trendy, I'll probably have to change that, too. Aaron, you have my sympathy.]
