Just keep creating, after a while you'll notice you're getting more and more ups. I encourage anyone new to participate in the comments, it is good practice and you can get an idea of what others fond entertaining faster. Good Luck :)
Just because you're not on the front page doesn't mean you're doing anything wrong. It's pretty rare to make the front page, since so many memes are submitted every day. Just keep having fun on the site, is my advice. :)
