How is this not copyright infringement?<p>I visit <a href="http://rdd.me/etjavojs" rel="nofollow">http://rdd.me/etjavojs</a> and I get the content of a scraped NY Times article served off of readability's server. All the ads are removed and they added an upsell for other Readability products.<p>How is this any different from me copy/pasting articles onto my own blog and slapping AdSense on it?
As unnecessary as any other URL shortening; and features like this belong to user clients (and not content) where they're always available for those and only those who needs them.
