Je super, že je tu konečně někdo z Čech! But to my question, do you think that you are more popular back in Czech or in US? I know it's simple question, but I'm really curious about that.

Dobře, co tobě? I thought this would be your answer. I'm sorry about that, people are more curious about bad and tragic stuff than your accomplishments or your charity work. Well I'm glad to see it's doing great anyway and I wish you good luck in the future!

I guess it's just me being lazy...saying Czech Republic is bit too long so it's used in more formal situations. But when it's just like this or with friends, "Czech" is enough. So you're right "Czech Republic" is the proper way...but it doesn't really matter. Nobody uses Czechia or Bohemia though. Both expressions are really archaic and are the name of only one part of Czech Republic.

In case you're asking how we call our country in czech language, the answer would be "Česko"
