We recently covered socialmedian , which late last year was acquired by European business social network XING , when they introduced a nifty application on the Facebook platform that allowed its users to share personalized news from across the web with their social graph. As of today, XING users can install the first two applications on its OpenSocial-driven platform: one (Xing News) takes the entire concept of socialmedian - personalized news filtering and sharing - and transforms it into a straightforward XING feature, the other one (Ask Xing) is a tool users can install to easily ask questions to the XING community and get responses without ever needing to leave the service.
