No. For the simple reason that. Geniouses are not always great with english. Just becuase they are clever, smart, and creative. Does not mean that they always create the most grammar correct hubs. Keep in mind that even scientist's who come from America. Often need editors to make sure their studys and/or research also live up to the rules of english.
Some people may have great education, and still be bad with grammar. For example why would an engineering major, or someone with a PHD in biochemistry, have the best english skills. Not everything is about grammar. Would you rather have a personal trainer, that uses proper grammar, yet does not have the best ideas for you to get in shape. Or would you rather have a peronal trainer, who is not perfect at using grammar, yet this trainer finds a way to get you great results and workouts.
I don't look at the grammar. If it is easy to understand, and the content is good. I will accept it. If the hub is not understandable, I will just leave it alone. You don't have to punish people if their hubs are not understandable, they will punish themselfs. If people do not understand their hub.
If we had the mindset of not paying attention to something just becuase it had bad english or grammar. There would be alot less knowledge and inventions in this world. Not everything is about grammar.
