The scope of the project is huge, suggesting a vast wasteland of empty page shells:
YouTomb, which launched about two months ago, is currently monitoring close to a quarter-million videos, and Jansen says the team is eager to expand its scope. Currently, the site only monitors popular YouTube videos...It's worth comparing these pages to Gothic architecture, which was originally based on buildings emanating from power, but rendered uncanny by the passage of time. YouTube lacks the military, aristocratic, or ecclesiastical context for 18th-century structures, but quite readily conforms to the corporate power of our time.
