Right now they are purely focused on American government, situations and Economics news regarding the USA.
I think it is not exactly fair for a site with a wide global reach.
Why not write one with a more global or local(non-US) focus? Be the change you want to see on mises.org!
But they are all the same type of problems. Besides, anybody is free to setup an exact replica of mises.org in any other country and write whatever articles they want that concern their local state of affairs.
I’ve read quite a few articles on Mises dealing with Europe.
