This video goes over the basics of shorting bitUSD: http://youtu.be/5BV55IrZi7g?t=4m4s
Most of us here saw that video. It's too dated. A lot of changes have been made since then and it's not helping with the actual Bitshares X interface. That just explains what BitUSD is and how market pegs work.
But it doesn't take people step by step showing them how to short, how to go long, or explaining the risk vs benefit from a bull perspective.
This may be of use

Investopedia is a great learning resource.
Anyone can tell everyone "short BitUSD" and show a generic URL on shorting.
That doesn't show you how to use Bitshares X. You're talking about concepts when the problem is even expert traders will be confused by the interface and none of them have seen anything like this.
So even if we know what a short is, it doesn't make the interface less confusing. Someone has to show how it is done just like any other new software which features trading.
Step by step, how do you short BitUSD in Bitshares X?
Now make a video (or at least a series of snapshots) showing everyone how to short BitUSD for profit. Show how it is done otherwise people are going to get something wrong, lose their money, or not take risks.
A script should basically be "this is how you do a short on BitUSD and make a quick profit as a bull".
Step one, "click the short tab" *attach image*
Step two, "enter the values here, understand that this is BitUSD and not real USD, and that you're betting on the BTSX price to rise in relation to it" *attach image of price chart or graph*
That kind of stuff. But if we assume everyone is both an experienced trader, somehow able to understand what BitUSD is, and also able to figure out the interface mechanics which aren't self explanatory, it's a recipe for disaster. Just my take on it.
If I can I'll make some images myself but the ideal is we need to set up some blogs or something so that people can follow along with an expert trader. I don't see how it can hurt and if you're the person who knows how to use Bitshares X well then perhaps you're the best candidate to make the blog.
