So, what is Docker and why should we care about a 0.x release? Yes, I looked at the link and no, I was not much the wiser, something to do with virtualization perhaps?

If you click on the project name at the top of the page, you'll find a README which starts with:
Docker complements LXC with a high-level API which operates at the process level. It runs unix processes with strong guarantees of isolation and repeatability across servers.
Docker is a great building block for automating distributed systems: large-scale web deployments, database clusters, continuous deployment systems, private PaaS, service-oriented architectures, etc.

For a lot of people that's not terribly helpful. Before I heard of Docker I had never heard of LXC.
Maybe, "Docker is a system for creating and deploying self-contained application packages for Linux," except I'm pretty sure "application package" is the wrong phrase. But that's the gist of why it's interesting, IMHO.
I agree the wording is not super approachable. We have plans to change that :)
I found your 5-minute video at docker.io much easier to understand—great presentation!
It looks to be similar to freeBSD jails
Actually, Docker is like a manager of FreeBSD jails :-) LXC is like FreeBSD jailing.
