APRS can be used for regional messaging. When I travel (all the time for work) I always have a rig set for APRS.
Some areas have APRS beacons giving local information about repeater frequencies, tones, and nets. Some have set up APRS beacons for hospitals and police (location type beacons). I have encountered beacons giving traffic/road construction/road closures information. Others setup APRS to beacon weather warnings/watches for the local area. Not to mention many times I have been driving in an area and get a "text" APRS message from a local ham, they just say hi and give me a local frequency to QSY for voice comms.
My kids have my call sign and information to lookup my location online whenever they want, if the ex allows it. This allows another method to stay connected to dad and my life when I travel.
It is a real effective method to mass broadcast a simple message over a local area or a region (if digipeaters are available) to many people. APRS can use digipeaters to increase the area serviced if needed or not use a digipeater to keep it very local. It is simple, relatively inexpensive and for the most part automatic if needed.
Exciting, not really.
