It's the data, stupid!

All this hysteria about Apps is causing a very scary result the micro-silofication of data, making it ever more unreachable. The previous data micro-silofication era, based on the mass production of spreadsheets at least kept the data accessible.

Why are we giving up access to our data so readily?

What will it take to have us realise the significance of this problem?

Where can I put my data?

The meter readings of my energy and water consumption for example whether automated or manual...

Ideas welcome...
