Absolutely. "If you're trying to found a company and get venture funding from Americans, you need to be able to communicate well with Americans. No one is saying there's a correct way to speak anything, but it's obvious Paul Graham is talking about founders going for an American market." However a big part of startup accelerator is about helping the founders gain the skills needed to be successful. No reason communicating well with Americans shouldn't be one of those skills that help is given for. "That's just straight out wrong, sorry to say. There are plenty of cases of one way unintelligibility in ALL parts of the world, in many languages. English is no exception, just consider the stereotype of American tourists being confounded by Australian or England-English." Yes it can be mostly a one way problem but there will always be subtle problems in both directions. I'm a UK native and have been living in the US for many years married to an American wife. We still come across words or phrases that confuse each other.
