It's alive and kicking on HN as well. I suspect that a lot of people here simply aren't aware that it's a thing, so unless somebody goes around telling people that they're left libertarian (and then explaining what this means), the corresponding specific policy positions don't necessarily get construed that way.

While we're at it, a reminder that economic left/right distinction is not the same as command/free-market:

Radical left libertarianism dates to the 1850's with Dejaque. Right libertarianism is a century younger.
