I really like the indicator on posts, it rounds the language feature and looks nice.

I think the disclaimer in the settings

Warning: If you deselect Undetermined, you will not see most content.

is perfect as well.

Two questions:

• why is this disclaimer shown when I create a post?

Warning: If you deselect Undetermined, you will not see most content.

Maybe this is meant to say this:

Warning: If you deselect Undetermined, most people will not see your post.

• I post in English and German and it is a little bit annoying that I always have to choose a language when posting. What about another setting, where you choose your default post language? You would have to choose a language that isn't undetermined which then will be preselected in the drop down menu when posting/commenting. This would make it so much easier for me. Would that be hard to implement? Or clutter the settings too much?
