@alecui To a point I agree.. if you are being artistic, poetic, or even just informal with your friends, then speak or write however you think is cool. But the truth is if you want to write for a journal, write formal letters for a company, or even just write professional blog posts, then you need to know the rules, and follow them. If you dont you just look uneducated and worse yet, will do a poor job at communicating your ideas.
