I hardly know any grammatical rules, but I don't make very many grammar or spelling mistakes in communication forms where correctness is desirable (customer emails, letters, articles, blog posts). Why? Reading heavily from age 5 to 18, means I have a built-in spelling and grammar checker. I grew up when there was no Internet or mobile phones at school going age though, doubt this is easy to get kids do these days. On the other hand, in IMs, text, or IRC, I write in all lowercase, don't care about typos or grammar, and it's very fast and loose. OP needs to learn how to tailor their content.
