Look at the incredible post Peter Shankman just put up on his HARO site:
OMG I love this!! This HARO is thanks to Hope is in the Cards, a
grassroots effort to generate 300 million upbeat messages
throughout our country. The idea is simple – get everyone in
America to mail one positive card or letter to someone else, right
now. How cool is that? Check out http://HopeIsInTheCards.org, but
even easier? Send a positive card or letter to someone today, or
write the word HOPE on the back of anything you mail. This is
probably one of the most wonderful things I’ve ever heard. Tweet it
out, they’re at http://twitter.com/hopeinthecards – It deserves it!
How can you thank someone for such good words? It is so humbling and wonderful!
