Every bit of information that we can think and share is a meme.
“Memes (discrete units of knowledge, gossip, jokes and so on) are to culture what genes are to life. Just as biological evolution is driven by the survival of the fittest genes in the gene pool, cultural evolution may be driven by the most successful memes.” —Richard Dawkins
I received a chain e-mail saying that If I mail the person who sent me this $1 and forward the e-mail to all my entire contact list, I will be a millionaire. There are hundreds of email addresses in the body of this email from all the forwards that have happened before it was forwarded to me. How cool! Unrelated: how are all these spammers getting my email address? I only gave it to all my friends and family. And my friends/family only send me cool chain emails and funny jokes. e-mail is a new technology, so surly they will fix this spam problem by the year 2000.
