I looked into Sia since it's something I'd love to see working and I'd heard of them before. Last time I'd found that the biggest tutorial about how to practically get started had a big red warning and a huge manifesto about how Sia and its collaborators are the worst and should be dropped [0].

So now I went around just looking for old links to files on the network, on places like Reddit and old guides, to check if they'd survived a couple years. Sadly all of them timed out, even the first link on the 'video' category on the Sky App Store. I looked up the error ('failed to create Skylink') and nothing of help turned up to even realize what the problem is.

Hopefully things work out in the long term but I haven't been convinced yet of Sia's usefulness in practice.
