Meme

Wiktionary defines a "meme" as being

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.

And memes are really something. Unless you're a common web goer, then you won't know what a good meme is. Basically it can be anything from a quiz, to an image macro, to something that you can say. As long as it fulfills the above definition, it's a meme. And memes are EVEYWHERE! From LiveJournal to your average forum.

An example of a meme, let's see, is the Drawing Personality Test; common with the more artistic folks on LiveJournal. Par example:

You tend to pursue many different activities simultaneously. When misfortune does happen, it doesn't actually dishearten you all that much.
You have a peaceful mind, viewing the world with calm and serenity. To you, life is not about struggle and strife but about existence and co-existence.
You like following the rules and being objective. You are precise and meticulous, and like to evaluate decisions before making them.
You have a sunny, cheerful disposition.

An image, in this case the interactive part of the test, then some made up thing supposedly derived from that image. This is what most memes are made of. Interaction and result. The result is the only reason you interact, and to interact you must pass through webpages of adverts. Thus memes equal money.

Awesome win.
