I found this Future of Real Time interesting.
Social media is another tool that is being used to monitor the well-being of communities. Online buzz around certain subjects can serve as an indicator of group sentiment, providing insights that are relevant offline and pointing to actions that can be taken to remedy problems as they arise.
Simple solutions are developing that allow people to connect rapidly across mobile networks. Government and aid-organizations are putting this newfound ability to use by creating temporary networked communities to handle situations on both a large and small scale. While others are putting this technology to use to instantly map geography, layer in information from other data streams and create context and narrative where none previously existed.
The proliferation of low-cost sensors has created also network of intelligent infrastructure that can allow for the monitoring of changing conditions and statuses in both natural and urban environments.
This report provides a lot of recent advancement in the use of technology in real time and an useful summary on social media.
Good food for thoughts.
