... We need a storage platform that people love using...
Yes, nothing else actually matters. Nothing.
Please read the Steve Jobs biography....
Obsession with "user experience" built the biggest corporation in the world.
You're mostly on the right track with Sia...
But running 3 programs, console interfaces, excessive locking, multiple passwords, lost coins, required router settings, dodgy upgrades, etc...
Show that you really DON'T GET IT... and are the sort of person Jobs would fire on the spot.
With BitTorrent, I can download a torrent with exactly 2 clicks... it's not too late to make Sia work.
Just luv your critical encouragement Zer0Sum

All said, if that is all you find wrong with it thus far, to me that means Sia is on the right track

when you consider its still very much in Beta......
By far.... it is not to late, to the contrary, its only just the beginning

PS: Even Steve Jobs and Apple were not always on top nor did they start out at the top....and went through many twist and turns and growing pains.... before Finally becoming one of the largest corporations. To your point I think the team with Sia is doing an outstanding job when compared.
