@WSama let me post this here and I hope others will find this resource useful as well. Opening Principles is a foundational cornerstone of chess and can help most beginner to intermediate players a lot. Even GMs use this a lot and so should the rest of us too! 
Thanks @KeSetoKaiba for the interesting read. Definitely a helpful post. Though I'm not a mod, and you're free to post on this forum as you wish. I simply hope that everyone will respect the concept of this thread.

I'd also like to point out that this is not a discussion thread. A simple link would be appreciated, and a brief description would be helpful.
I've added a discussion thread here, if anyone is interested. Separating the two will probably help keep this little list navigation-friendly.
I've created this thread as a way to list some of the most fun reads on chess.com. If you've found something shiny in the sand, you can post it here. It doesn't have to be chess related.
Here's how it goes:
