I mean no disrespect, but purely from how you phrased this - I hear things said of this form a lot - this sounds more like your problem than Sandstorm's.
That's quite valid :) However considering Sandstorm was crowdfunding, and I was interested in their idea and so did a minimum of reasearch and followed all their posts, I'll retort that in this case, it's their problem.
As a counter-example, it was pretty clear to me what Cap'n Proto improved over ProtoBufs.
perhaps, but assuming Sandstorm is a commercial venture and desires to make money, it IS their problem to educate prospective customers on their value proposition. we know what docker does.
