Be funny, original, and creative. This can actually be a challenge because what you might find funny might not be funny at all.

Ways to think of good, funny ideas is to read funny books like A Hero's Diary and The Ultimate Pun Book or learn from popular goofballs like Bad_Katt and TypicalTavi .

Of course, you should be yourself, but you should also put in more effort to be funny. Otherwise, high popularity would be just a longshot.

I can't really help you too well when it comes to increasing humor, no matter how funny the diaries are. That's why the least you can do is learn from online society.
