Embedly - About: "Embedly, Inc. provides a service which makes every URL on the internet embeddable for any website or web application in which it is posted. Currently, we serve over 500,000 embeds per day to over 200 sites.
Embedly works on the notion that links do not engage users unless they have relevant content around them. There are numerous links moving quickly through the internet everyday via social media and news sites such as Twitter, Facebook, Digg, and Reddit. Click-thru rates are being reduced as the amount of links multiply."
