They could be applying the grammatical rules from whatever language they predominantly use/mother tongue to English, and we see this in their postings.
It's easy to tell those for whom English is a second language, and it's even easier to excuse the errors in it. I'm thinking more about English-speaking students who don't know when to use 'have' or when to use 'has'. They don't know whether or not they should follow a question or exclamation mark with a period in order to end their sentence. They don't know what an apostrophe is or when to use it. They don't know the difference between past or present tense, and they don't know how to make present tense into past tense. They don't know how to conjugate verbs. They don't even know what 'conjugate' means'.
These are simple, basic rules of language. Without them, communication becomes difficult if not impossible. For many of them, if they created a resumé, it wouldn't even get them a job in McDonald's. I understand that grammar is difficult for some people, but it baffles my mind to see someone as confused about when to use 'colour' or when to use 'color' as they are about when to use 'a' or 'an'. It's a frightening future if nobody can understand each other.
