Yeah I didn't either, until not too long ago but now I'm pretty excited to use it.

As a person who wasn't a linux admin back in the 90s, and doesn't normally hang out on mailing lists, the first time I saw lxc was some random article on lwn.net (I don't hang out there, but they have some super high quality articles), and I definitely didn't put together how much of a difference it was poised to make, or even know why it was a good idea (people were still getting used to vagrant everywhere at the time) -- docker definitely did the community a service by bringing the hype train, if only so that once the hype subsided containers would be here to stay.
