I notice a lot of your memes don't get a lot of votes, and I think it's because you are churning them out in a great quantity. You cannot have good quality and high quantity. Same goes for comments. A generic "LOL" doesn't go a very long way.
If points are you only motivator here I will tell you what is a fact. If you focus on making a few quality memes each day, and making good legit conversation you will get MORE points. Because you will have something more worthy of an up vote. A blank image of someone laughing just isn't as funny or interesting as a relevant comment is. So you will find that you must make more comments to try and get ahead. People view this generic activity as point panhandling. You have made triple the memes I have in your few months here, and honestly we are doing about the same in the points department. My activity is up one day and down the next, so I do fluctuate. But really, we aren't that far apart. I also don't do it just for points. I draw genuine enjoyment from a good meme thread. You will rarely see me make a generic comment. If I don't have something relevant I up vote and come back later if I think of something.
Anyhoo,I know you didn't ask me but I just thought I would put that out there.
