Once users, organizations, collaborations and software are registered, we of course want to be kept informed of updates and announcements; we want to get in touch with users or developers with similar interests; we want to know of new releases of the software we are using. In a word we want to exploit the advantages of having a network of relationships with people, projects and software products. This is the typical feature of a social network and ScienceSoft is indeed a specialized social network across a very diverse community of software developers and users within larger scientific research activities. It must be possible for users to create relationships based on their own interests, follow other users, create or become part of dedicated interest groups focused on specialissed topics. We don't presume to be inventing anything here, we rather look at what other successful social networks are doing and provide similar functionality on top of the special information we handle in ScienceSoft. Collaboration and integration with existing social networks is very necessary.
