People would want to go to the page, Wikileaks, to find out about Wikileaks. Not about silly cables they write. Think about it. When you look up an article about water buffalo, you want to read an article about water buffalo, NOT about the prairie grass they eat. Write things about how Julian started wiki leaks, the history around it, its legacy, its mission statement, etc. However, You did start out with the right humorous tone at the beginning. Just keep that tone and write about wiki leaks itself, not its cables.
Not everyone likes cursing. There are exceptions, like say an article about polite language. Wikileaks is not one of them.
I suggest Reading the beginner guide. It's the holy grail of all humorous writers on Uncyclopedia.
Wikileaks is famous, it's controversial, and it's a great potential for loads of laughter. Is there anything more to be said?
Prose and formatting:
Perfect formatting to start, bad formatting for the cable. All caps is difficult to read and enjoy. The cable should be moved to an article titled, say, Controversial cable on wiki leaks once it is done in proper sentence structure. Each beginning of each sentence should be capitalized, and sections should be added when appropriate.
There are no pictures whatsoever. Add pictures immediately! I beg of you! Even if it's just a picture of your cat, adding pictures can improve an article drastically. Adding pictures will make your article, and the world, a better place. Don't forget to add captions to your pictures. If you don't know how to add pictures, read Forum:How do I upload images?. It will answer any questions you have.
Talk about wikileaks, not it's cables! Move the entire article to an appropriately titled page such as "Controversial Leak from Wikileaks cable" immediately. But keep the same writing tone you had at the beginning. That's the kind of tone people want to read around these parts, not the "LOLZ! I JUST F***ING SHOT MY FOOT WITH A MARSHMALLOW GUN" tone.
Change the article immediately if you don't want a big, mean, admin to see and delete it. The article has been huffed so many times it's not even funny anymore. It would be regrettable for the article to be put under permanent deletion...
