This demo allows you to try a Web Intent which picks a profile from another web site. It request hCard as its data format and expects the return hCard data to be formatted in JSON. It uses Paul Kinlan’s Web Intents shim
You need to vists the profiles page first.
Then click the pick profile buttons below and select an option from the pop-up window. The shim is in constant development, I found it’s best to test its use with Chrome.
