I would for sure take Socrate's advice, he was born a top user. One thing that helps is making lots of comment memes and watching them to see what others find funny. One mistake new users make (myself included) is assuming EVERYTHING you find funny, others will too. Making lots of comment memes accomplishes 2 things. !. you learn the "craft". 2. You get seen, and as your comments get better more people will look at YOUR stuff. Just remember like Socrates said though, you never know what will work, I've had some I spent a LOT of time on do nothing, while ones I did in 2 minutes to quickly get my last submission in before bed, made the front page. So the moral of the story... participate and have fun!!!
