I really like the idea of the private blockchain @nice-guy-eddie. This would definitely be something I'd support instantly as it's not really fair in my eyes that those big data companies just use everything to make money but don't give anything back. Your Data should be your property and like you mention above you should be able to decide what's going to happen with it.

But let's see what the future brings to us. It's definitely a very interesting tim for all of us.
