Yahoo! is encouraging its users to share kindness with the whole world and let others learn about the good deeds. Once you do something nice you can tell about it to the other people, creating a ripple of happiness, and inspire others to join you by asking «You in?«.
The more people know about your act of kindness (like donating money to charities, giving clothes to homeless or feeding alley cats), the larger your ripple is. On the website launched for the campaign, you use the tweeting system to tell people how and where you shared you love. For posting the information you can employ all kinds of social networking (you just pick out the one you prefer from the long list).
Every deed is marked on the interactive world map with a purple heart, the major colour of the Internet brand. You can even make a photo with the person you’ve helped and upload it as here, on Flikr.
