Those topics that people who are Austrians are interested in, but is not Austrianism itself, are also acceptable. Austrian economics is simply the backbone.
EDIT: let me rephrase that. What I mean is: if a person has a topic, that he would like people who are Austrian’s perspective on, are accepted. So “what is a good diet” is not accepted. But “what kind of music do Austrians listen to” is; because there can be a correlation between the two.
Perhaps the sidebar needs rephrasing.
