Just curious but what is the fascination with watching ADS-B screen data ?
For me it's like watching paint dry but this may be because I spend all day doing ADS-B commercial transmitter designs ?

It's a great thing for monitoring. For me, mostly all I use it for is milcom. I do feed to Plane Finder, too. It's also nice to see what friends are departing from the local airport and what they are doing (with unicom on, too), even just with MODE-S. Besides that, for me, the glorification lies in all the tankers, and interesting military aircraft, like E-3's or such that can bring large activity into the area.
If your asking why do I listen to milair? Because I am fascinated with military aircraft, and I am planning to go in the Navy to be a pilot. Being a pilot, (specifically military) communication is a big part. If I make it to the Navy, I'm going to know tons more about flying from the experience of having a pilots licence and even a bigger step up with communications compared to the guy coming out of college that has never flown a Cessna before or doesn't even know what a pitot tube or VORTAC is. So yes, it is just a small part, but it has a link in with all the other things I do related to aviation

I'm one of the few young monitors, so I don't know what the elders story is.
Anyways, Hope that helps! That's my story atleast!
