Why do you need to communicate in English with us native English speakers? Why don't we need to learn your language to communicate with you?
The way I'm looking at it is that you're putting all this effort towards learning how to communicate with people who would never without an outside pressure do the same for you.
If language learning is intrinsically a positive thing what can we do to encourage it in native speakers of English, specifically Americans who are monolingual (as they dominate this website)?
Imagine a scenario where Dang announced that we're only allowed to post in English one day week -- every day is dedicated to another language, like Spanish, Russian, Mandarin and the system auto deleted posts that weren't in those languages. Would that be a good thing? Would we see American users start to learn Spanish to post on HN on Tuesdays?
