Facebook Turns Apps Into Widgets With Custom Tags

Today Facebook will announce the launch of “Custom Tags”, a new feature which enables developers to extend functionality within their applications to other applications on the Facebook platform. The concept is that applications can launch their own version of FBML tags, ultimately enriching the overall feature set that developers have access to within the Facebook platform. Yariv Sadan, the engineer behind the feature, stated that “FBML is great for developing pre-built components [and we wanted to expand that functionality to developers].”
