A few I just couldn't do. I had no ideas for comments! I upvoted every meme though. I will say, as far as your memes, gaming memes do tend to get less comments. This is because the site is mostly full of older people, (Like your parents age at least) who aren't as interested in games as they used to be, or the games they like are not the ones most popular here. So if you are looking to really get more activity here in general on your memes try branching out a little bit. Do some gaming but then try to get in a few that relate to more people in a common way.
It can be a task getting in with the community. But if you enjoy the meme wars and like interacting in general you'll have more fun. People who are just here to climb the top users board are usually not having as much fun as the rest of us! Anyhoo, happy meming!
