The "card in real life" posts are interesting once in a while, when the image isn't something as generic as this. It's like I could take a picture of a tree and say "oh em gee a forest card IRL"

As for people hating on the cupcake posts, I think that is unwarranted. It's an expression of love for the game we all play, and it's delicious too.

Finally, what you refer to as a meme is actually an image macro. That's what the images that come from quickmeme, meme generator, etc are. A meme on the other hand is simply an idea or concept that spreads within a community. To use a relevant example, the whole Storm Crow thing is a meme.
