What is your goal? To become one who creates good memes which are creative and original, or just to get memes on the front page? To get in the top users board, get on the weekly leaderboard? To all of these my answer is.... (drumroll please....) Just be social.
This accomplishes all of that. When you get out there and socialize people will visit your page, and upvote your memes, and comment on your memes as well as the comments you make with them. Also make sure you are up voting in return though. It's rude if you don't. This activity will get your meme in the "Hot" pages, and likely land you on the weekly leader board, as well on the top users board also.
HOWEVER. I also don't recommend this if your heart isn't in it. As the comment activity will feel more like a chore if you do not truly enjoy it. I love meming with my friends here. It's fun, and a great way to unwind and have a laugh. It also gets the creativity flowing. The improv in comments stretches your brain and sometimes good ideas come from that creative exercise.
Try making some of your own templates. Many of us enjoy taking an idea and editing existing templates, or making a new one from photos we took, or dug up in a search. However, I will say sometimes memes that we think are our best may not make it to the hot pages. I have had some go over like a lead balloon when I thought they were the best thing since sliced bread. It happens to us all.
So yeah. Have fun, be social, run with the ideas that cross your mind, and write them down so you don't forget what they are. That's all I got. Several paragraphs of advice. LOL
