This threatens to supplant metal detectors as the worst hobby in the world.

Evidently thousands of hobbyists worldwide have launched weather balloons designed to be neutrally buoyant in the jet stream, and are inhabiting them for hours each day (some full-time) via telepresence. By convention one balloonist only communicates with another if their balloon is within a narrow radius of the other, so it’s a high lonesome way to spend your free time. I predict tree-telepresence will be next.
