Actually, sneakernet social media is highly appealing.

I like the idea of of receiving social updates through a USB stick or Bluetooth or NFC.

I once read a story about how the Tuareg people of the Sahara improvised a vast sneakernet file sharing network using Bluetooth.

This was needed because there's not a whole lot of cellular networks over there. And some Tuareg are nomadic, so WiFi isn't an option either.

Some incredible music was shared this way. I think it's how Mdou Moctar for discovered.
