I agree that the most important thing is being understood. If I have to read what you write two or three times in order to understand it, not because it's complicated, but because
you're not making any fricking sense, there's a problem.
Curiously though, I like ~~NeYo~~. He's got style, even if I'm a bit skeptical about his syntax. And he's always so upbeat about everything that it's hard to dislike him. In my opinion.
But I think that it's good to pay attention to the details too. If two people are having an argument (um, I mean "debate"), and one person says, "I think your wrong about that," I'm instantly going to take that person a little less seriously. If they speak English and can't put in the effort to make sure their grammar is right, I get the impression that they just don't care enough to polish a little bit, and that will negatively affect how I view their argument.
So while I like ~~NeYo~~, I do find it
extremely difficult to take him seriously.
