It didn’t take long for someone to hack the first OpenSocial application. In fact, it took just 45 minutes.

A developer who goes by the alias “theharmonyguy” and describes himself as “just an amateur” claims to have compromised the RockYou OpenSocial application on Plaxo called emote (see the Plaxo blog for details on the application). Specifically, he claims to have added a number of emoticons to Plaxo VP Marketing John McCrea’s profile within 45 minutes of it launching.
