Zaflow 
Zaflow facilitates group communication through information sharing in Real-time. It allows people to share things like ideas, questions, polls and then collaborate around them. Posts are grouped into time lines called “flows” that make it easy filter out content that is relevant for them at that moment. Updates are securely shared and available only to the group members. Zaflow works similarly like Twitter and its follow network, but innovates with enhanced content filters, group distribution and location-based messages.
