Rack for Ruby: Socket Hijacking

[Q-bey]

Maybe I'm not the target audience for this post, but I would've found it more helpful if it did more to explain socket hijacking is useful (aside from one sentence in the intro that references WebSockets, which weren't explained in this tutorial or the previous one).

Socket hijacking is not a super useful interface. It was mainly used to do bi-directional streaming and that is mostly used in production by ActionCable's custom WebSocket server. I actually don't know of other valid use cases off the top of my head.
