I feel like the representatives of GoScale here are not doing themselves much good. They offer vague answers and hand-wavy descriptions. We all get that you have trade secrets. But If your business is jeopardized by just describing how your infrastructure works, that should worry you.
This is your "Show HN." You chose to do this. You should be generating excitement and buzz. I suggest taking a look at how Dropbox or even Tarsnap have talked about infrastructure in comparison to how you're doing it here. Talk about what you've built. It will spark respect and excitement around your brand. Lots of people have a real affection for Dropbox. That doesn't happen on accident.
I'm sure my advice here isn't unequivocally good. But it's a counterpoint I think you should consider.
