English is not my first language, but having learned it allows me to consume content from the English-speaking world and SOME content from non-english speakers who choose English (and rightfully so) as their net language.

I'd love to learn other languages to be able to interact with more people and ideas. Imagine speaking English, Mandarin, Spanish and Arabic. Being able to communicate with over 3 billion people in their own terms. Engage in the discussions that they're having about their lives, in their words. That would be great.
