To meme or not to meme. That is the question. To meme of course but what is a meme?
A meme is an idea blueprint. If you have seen the blueprint or exposed to the idea then you understand the joke. If you can rebuild the blueprint in another way, that propogates the meme.
It evolves, and like DNA it passes on the traits it acquires. You can see the Memes Evolve.
We are Memes, our genetics and our education are all memetic frameworks of meaning.
As Terrence said, put your meme out into the universe and see if it propagates.
