Yep, we fell for the "good products sell themselves" meme. :/ As engineers, we felt uncomfortable promising the moon like so many other ICOs did (and still do). Blockchain-wise, the system we built was actually very conservative: aside from the file contract payment channels, our consensus design doesn't stray far from Bitcoin. As it turns out, the blockchain is the easy part! The hard part is, once you've got your network of hosts, how do you turn that into a truly great product? Sia is crazy cheap, it streams video at 1Gbps, it's got plenty of 9s, but those metrics don't mean anything in a vacuum. We've finally hit upon a more user-friendly product in Skynet, and we're doing a lot more PR this time, but we've still got a long way to go.
