Yahoo is asking its users to come together this holiday season and make a difference through simple acts of kindness.

The campaign, called “How Good Grows,” encourages people to do random acts of kindness and update their online status to get others to join in.

The kindness.yahoo.com website allows people to post status messages that can be shared across their social networks (Yahoo Updates, Facebook, Twitter). People can watch their ripple of kindness grow on the site as they inspire others to also do kind acts. The ripples will grow bigger as more people click on the status messages and do kind acts of their own.

“We are inspiring millions of people within the global Yahoo community to change the world together through random acts of kindness. One small act of kindness can create a ripple of generosity — that’s how good grows on Yahoo,” said Erin Carlson, senior director, Yahoo for Good.

“It’s simple — do something nice for someone like pay for a stranger’s cab fare, volunteer at your local soup kitchen, or make cookies for a neighbor. Update your online status, get others to join in, and watch your ripple of kindness grow.”
