Points are a way for people to get an ego boost when their memes and comments get likes. Dislikes drop your points (which is some BS really, but what can ya do?). Koshe explained it well. As long as you use then, than, your, you're, and their, there, and they're properly, you will do fine. I wish you luck grasshopper. You already have a meme with 11 likes, way to go :)
