I just came back from an evening at Google, where I and a dozen people exchanged new OpenSocial applications ideas. The goal of this session was to define a few projects that will be implemented during next week's hackathon at Fujisoft.
The project I had sketched up in the train in a hurry is one those that will get implemented. It will allow anyone to easily create rating systems in social networks services, where ratings will hugely benefit from being shared and receiving friends interaction. I will describe this new project in details later. It will be open source.
