Business communication is increasingly becoming social. Social business software is the next hot trend in business technology. As Generation Y joins companies, legacy intranet systems are becoming outdated and less useful while social networks and collaboration platforms are gaining popularity both internally within companies and for business use. Over the next five years, the majority of companies will have a corporate social network to improve information sharing, collaboration, productivity, and knowledge management among employees. This transition will be led by new roles like digital strategists rather than the IT department.
