On some site it's almost like a competition to see who can be the rudest to somebody and get a reaction. They come here and aren't used to being told they aren't welcome. Though there are many ways to exploit and manipulate points on here that some take advantage of. It's kinda silly because in the long run you either make good memes or you don't. All the points in the world on this site aren't going to get your meme to go facebook viral. But a good meme with little points always can if it's good enough to be shared and original it will be. I've had many people comment on memes that are over a year old because they got passed around somewhere. You can fight for points here, you can be a big deal even, points just can't make you go viral all over though. Only funny original stuff can do that, just be true to yourself and your type of humor. Make memes that make you laugh as you are creating them. If you don't enjoy doing this and need points to make you happy about it, you won't last long term doing this. It has to be fun to make a meme that gets 1 upvote or you will end up making stuff just to get points and then the level of creativity drops immensely.
Just my opinion, it's up to you to decide if it is worth anything ;)
