I have been wondering for a long time what exactly is a meme. I always forget to find out, but not today. I looked it up on wikipedia and got this definition from the wiktionary.
meme (plural memes)
1. (philosophy) Any unit of cultural information, such as a practice or idea, that is transmitted verbally or by repeated action from one mind to another. Examples include thoughts, ideas, theories, practices, habits, songs, dances and moods and terms such as race, culture, and ethnicity.
2. (philosophy) A self-propagating unit of cultural evolution having a resemblance to the gene (the unit of genetics).
Now, don't you feel smarter knowing that? I sure do.
