While doing a websearch for memetics, I found a website which linked to this website: http://www.generosity.org/ . The basic idea is that it encourages people to do the following:
    -Do something nice for someone. Do it anynomously.
    -Leave behind a cardsaying:

This is for you!
Now it's your turn: go do something good for someone else.
Do it anonymously.
Pass on this card.

    -Hope that whoever got the card will continue the chain.

    It's a bit like the concept of the movie "Pay it Forward", but whithout the exponential growth (and it doesn't have to be something really big - you can just pay for the next client's coffee, or something like that). It's an interesting concept - and possibly an efficient way of recruiting vectors for the generosity meme.
    Opinions?
