From Wired:
Imperceptibly and all but instantaneously, your post slips into a vast and recursive network of software agents, where it is crawled, indexed, mined, scraped, republished, and propagated throughout the Web. Within minutes, if you’ve written about a timely and noteworthy topic, a small army of bots will get the word out to anyone remotely interested, from fellow bloggers to corporate marketers.
