FB/Google/Instagram etc. serving content, and AWS/DigitalOcean owning the hardware for those intrepid individuals who want to roll their own solutions.
The internet wasn't supposed to be Amazon, Google, and Facebook all talking to each other. It's scary that ISP's don't even want you to host your own (modest) server. It's SUPPOSED to be a bunch of computers networked together! Sandstorm makes it easier to live that vision where you own the hardware, or at LEAST have full control over your cloud. It doesn't necessarily need to be your home computer - a colo'ed odroid (or RPi if your needs are modest) would do the trick too. As more and more of the internet is gobbled up by VPS services I think it's important that the average Jane or Joe can still put together their own website, blog, game server, etc. and not be reliant on a company for it.
