There is a chicken-and-egg thing too - it's not normal for Joe Internetuser to have a $5/mo cloud server in addition to his Netflix/Hulu/etc because there is no easy-to-use-for-regular-people software to run on one, and no one builds such software because such users don't have $5/mo cloud servers to run it on. This is sort of the fatal flaw of app portals like Sandstorm, but it doesn't need to be that way forever.
Well, you can use a managed version, both Sandstorm and Cloudron can be subscribed to as online services. I also think there's a lot of opportunity for families and small groups. Most people I am close with would not run their own server, but perhaps would use mine if I offered it.
