Cast Your Vote!
I hate these polls... because I like so many aspects of the different blogs listed... arrrrrgh (and point well taken, Aeon! :) )
So, I have to approach it this way--If I had a gun to my head ...
Best Libertarian/Classical Liberal Group Academic Blog: Mises Economics Blog
Best Libertarian/Classical Liberal Individual Academic Blog: Austro-Athenian Empire
Best New Libertarian/Classical Liberal Group Academic Blog: Szasz Blog
Best New Libertarian/Classical Liberal Individual Academic Blog: Theory & Practice (IT'S A LANDSLIDE!!!)
There are also blogs that defy categorization but that I regularly read, like Once Upon a Time.
In any event, go to L&P and Cast Your Vote! (The deadline is December 31, 2005.)
