When I say "less-mentioned" I mean "around these parts" - ie, the forums.
Generally, we speak very much of Rothbard and Mises but not exceedingly much about other writers in the Austrian tradition.
I started this thread because lately I've been becoming more and more convinced that a lot of the beauty in Austrian theory comes from the understanding of the entrepreneurial process, something that if I understand correctly is elaborated on in Hayek.
Furthermore, capital theory of Bawerk seems like it would be important to understand. And one should probably read up on Menger.
Just throwing these names out there. I think that I will be more and more fascinated with economics as I expand to read these other authors.
Edit - also, I've heard Lachmann is interesting as well.
