I like Docker, because it automates much of the LXC bits, and adds cool filesystem features. So, do not take my comments the wrong way, but I think articles like this do a disservice since they over hype!

So the internet endgame seems to be One Huge Reinvented Internet in a huge computer running Nginx. It could be worse.
Here is the home page of LXC: http://lxc.sourceforge.net/
Here is the home page of Docker: https://www.docker.io/
Reading both should answer this question.
I also would not categorize Docker as a 'little wrapper' around LXC. Sure, Docker uses LXC as a default container provider but it could have just as well have been raw cgroups/network namespaces, libvirt, openvz, or any other abstraction that suits the core abstractions of Docker.
Really? "Build a Computer the Size of the Entire Internet" based off LXC containers they're creating an abstraction over?
It's like saying virtualenv can "Build a Computer the Size of the Entire Internet" because you can relocate an entire python program easily.
I love how rabid they are, but self-promotional attention is getting out of hand.
[SELF-CHECK: If you find this article annoying to read, is it because you're jealous of their attention? Are there things you've done that have mattered (or could have mattered) if only other people paid attention? How are you going to get attention next time? Yeah, getting attention this way can seem slimy, icky, unseemly, and feel like outright lies, but they'll be the millionaires and you won't. Gotta get slimy sometime.]
Nobody's paying for advertisement of scp scripts.
