Ask HN: Idiomatic english for startup success

[3zzy]

I came across a TC article (http://techcrunch.com/2014/10/01/an-immigrant-experience/) that linked to PG's comment back in 2009 about YCs selection criteria and PG noted:

"One quality that's a really bad indication is a CEO with a strong foreign accent. I'm not sure why. It could be that there are a bunch of subtle things entrepreneurs have to communicate and can't if you have a strong accent. Or, it could be that anyone with half a brain would realize you're going to be more successful if you speak idiomatic English, so they must just be clueless if they haven't gotten rid of their strong accent. I just know it's a strong pattern we've seen."

It makes me worried because I've applied to YC and I'm not a native speaker. My english is less than perfect, and my accent is terrible.

Ofcourse this was in 2009, so I wonder if his views may have changed now. Did YC accept any non-english speaking founder(s) lately? Do you believe speaking idiomatic english is a necessity to run a successful business?
