I really like Sandstorm - it's a glimpse into an alternate world of how things could be.

I tried the demo, but I still don't get it. What is it? Is it supposed to be like a collection of productivity apps, like google docs/drive ? The demo worked poorly, I waited very long time for many interactions, some didn't work at all (like changing font on etherpad).

I agree the current experience is sonewhat unpolished. The docs explain the vision best: https://sandstorm.org/how-it-works

You sir know how to appreciate the simplicity such service providers deliver.

I'd not heard of yunohost, so I went googling and found https://www.reddit.com/r/selfhosted/comments/1ey9ayp/what_ma...

Seems like Docker has won so comprehensively that even more convenient (But unfamiliar) options are pushed to use it.
