Simon Willison beat me to a point my mind had filed away when I read the same Wired article this morning: attribution is good etiquette. Nothing complicated there, just if you write about an idea or post a link to something, also include a link to where you found the idea. It helps propagate ideas by letting people trace conversations, gives credit to the person who gave you the idea, and helps the magic interconnectivity that’s supposed to make the web, well, a web.
Simon has a cool show referrer bookmarklet. To use, just drag it to your bookmark bar/menu. Click it and it’ll pop up a window giving you a link to the site that brought you to where you are now.
