A dirty little secret about screen-scraping
Suppose you’re buying a new computer. You find a great-looking computer at a local store, bring it home, boot it up, and…it’s extremely slow. You open up the case only to discover that all of the internal parts are at least 10 years old. You storm back to the store demanding your money back because they sold you an old computer. Their response: “Of course it’s new, look at the new, beautiful case we put it in.”
