Young Writers Society

Well, reviewing might seem like a really simple thing to do, but too many times there are the short little reviews that say, "well, this is good, nice job", and not much else. Unfortunately, as sincere as these might be, they don't help you or the other person.
You see, reviewing isn't just beneficial for other people. It also helps you to learn how to write, because you learn how to identify mistakes, which makes you watch out for them in your own work. Reviewing well really helps you grow. Heck, that's how I learned how to write. I think that's how most of us have learned how to write.
Not only does reviewing improve your writing, but it gives you points on the site. You can get up to 50 points for each review, but only if they're long enough. You don't want to fill your review with half-hearted words and opinions with no backing; better to write something that will help someone, especially if it will help you too.
