Common sense is your commentary and adds personality and opinion to your post, which is good. What is common sense to you may not be common sense to someone else. Sources simply help to prove or illustrate your point. Citing credible sources will help attract more whales/dolphins to your posts and also with papers you'll be writing in high school.

Another thing: if you want to be a good writer, you have to read (books and articles you agree and disagree with) so you can write coherently, passionately, and respectfully, among other things.

O for chrissakes, give the kid a break -- he's 14! He writes better than i did when i was 20! And he is also correct in everything he says, or alludes to, in his article.
He's practising, talking the talk, and expressing some ideas. It's not up to him to provide you the exact details of the silver market, price manipulation, history, uses, global supply/demand fundamentals or anything else for that matter.

Holy hanna! This is a silver stacking post, leave the pedagogy at home.

Thanks for this reply. Just wish I could upvote it more than once.

He's my son, but nice rant. Thanks, enjoyed reading it.

If I don't help him improve, who will? Certainly not you or any other stranger. I happened to be at work when I read his post and wanted to tell him those things. It's kind of my job first and foremost to be a parent!!!

Well that makes it a little different... however, if you are going to insist on exactitude then i wouldn't be complaining about his grammar with a run-on sentence :P

I bet you're an amazing mother -- your kid is proof -- and only want what is best for him. And i agree it is your job to be a parent first and foremost. Sometimes, though, that is best achieved by lettin' 'em have a lil room to flap their wings.
