Hey Jetjock,
I want a pilot social app that alerts me whenever any of my pilot bros are close by. That is, I'd love being able to get a coffee or beer and catch up if any of my friends are gonna be around for a couple of hours... but I usually have no idea who is where. I imagine there are other apps o.k. for this sort of thing, but I'd rather keep it to pilot friends vs. my entire list of FB friends whom I rarely come across at airports. Food for thought.
