So I am working on learning how to use the Internet of Things with my Raspberry PI 2 and NodeRED flow manager.
Lots of really cool stuff you can do with it. It can check your mail or twitter feed or listen to rss feeds or web sockets or watch files for changes and lots of other sources of changing real-time content from the web or from connected devices via the serial ports on the raspberry pi. Then it can modify and make decisions about what to do with the flow of information coming through the flow system.
Really interesting system. I'm working on some artificial intelligence based twitter responder and email responder systems to help me connect with folks in an automated fashion.
