The RSS feed from DealNews is a classic syndication application, one that combines small pieces of information (product discounts) and perishability (one day only!) in a way that sends data to people and creates urgency and a compulsion to act. I literally find myself spotting something and thinking, “Whoaa, that’s a good price for hard-drives! And look at that Dell discount on desktops. Hey, maybe I need a new 20” LCD. And who woulda thought you could get memory keys for so little money?”
Of course, spending so much money on so many cheap things is also a straightforward way to go broke.
