From Ars:
One of the few survivors from the dotcom bubble that we know today as “Web 1.0” has now announced that it is moving firmly into the Web 2.0 world. The online auction site eBay announced at the eBay Developer conference in Boston that it has opened up its three core businesses—eBay, PayPal, and Skype—to third-party developers. These new application programming interfaces (APIs) are being released as part of a limited beta program: attendees at the eBay developer conference will get preferred access.
