gCube social facilities: news feed

The gCube social networking facilities manifest in a number of applications made available through a thin Web browser are conceptually close to the common facilities promoted by social networks - e.g., posting news, commenting on posted news - yet adapted to deal with large scale collaboration and cooperation on comprehensive scientific prod- ucts, data sets, theories and tools. The News Feed lists users' and applications' updates and make these available to every user according to his/her preferences. Additionally, it enables users to comment, subscribe or re-share these updates, and - in case of application posts - to make users access the subject of the post directly in the application that created it, e.g., to see a data set or an application.
