16:34:00 +07:00 Dear Duolingo: Are any words the same in all languages? - Absolutely fascinating post about culture and history and language and travel. I've never used Duolingo myself but I've heard lots of good things about their app. You know a company is really into their core mission when they write a blog post like this. Just brilliant. I wonder if they have a podcast? # blog.duolingo.com
