libertarian approaches to spectrum allocation and land use and transportation policy

Notice you didn't mention 'human rationality' at all.

From our vague semi-non-official guidelines:

Specifically, should posts be about rationality, or can they be "mere" applications of rationalist insights to specific topics?

The latter is a dangerous path to go down, at least for now. But if an application has something new to say about rationality and it's something that our already iconoclastic readers haven't heard before - i.e., not the standard arguments for libertarianism or whatever - then I guess so...
