Did any of you ever read The Selfish Gene? I'm not sure how somebody could read the book and not see how useful the concept of a meme is for understanding information; every-time you misshear a song and sing/hum the wrong tune a new meme is made; every single letter and symbol you've ever seen is a meme going about it's existence; every bad joke and good joke and variation on a joke is just memes shuffling around and being selected on. Every piece of scientific and mathematical knowledge is a finely crafted meme that can be used to influence the world and make more memes. Your strategies for making friends and getting laid is just you playing your memes off of someone-else's. This whole post and this website and your thoughts themselves are memes.
The information is everywhere around you and now you have a word that perfectly describes this, isn't that wonderful?
