In essence, you can:

- create/organize your data in hierarchically (lists of lists)

- publish content at any point in the hierarchy

- share data with specific people at any point in the hierarchy

- generate QR codes for any point in the hierarchy for mobile/remote access.

It's an idea I have been playing with for years, but finally got around to turning it into something usable.

It's actually pretty good and I think the concept is unique.
