accept is it is kind of difficult to type text into the radio. You can also have prepare few text messages a head of time, and just send the one you want.

But I am still searching on how people actually use it.
Packet radio in general is just that, packets that are just switched signals. It's just really high speed Morse Code and a very early form of WiFi. When you operate packet it's just like communicating via texting with a terminal program for your interface. Once you've packetized (hams generally use AX.25 framing) your link you do can anything you want it, just like the Internet itself, position reporting is just one part of it. You can do digital voice (this is essentially D-STAR), digital TV, time beacons, even Internet over the link, lots of things.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
