Max Gladwell of the Huffington Post wrote an interesting article today titled: 10 Ways to Change the World Through Social Media

For most of us, social media has changed our lives in some meaningful way. Collectively it is changing the world for good.

He showcases a list of 10 non-profits including SalaamGarage, an organization that leads trips that combine cultural immersion travel with citizen journalism collaborating with NGOs around the world.

The idea is that social media has enabled each of us to have an audience. Whether through Twitter, Flickr, YouTube, or a personal blog, each of us can have influence and reach. What’s more, it can be used for good. SalaamGarage coordinates trips for citizen journalists (that means you) to places like India and Vietnam in conjunction with non-government organizations like Seattle-based Peace Trees. The destination is the story, as these humanitarian journalists report on the people they meet and discoveries they make. Their words, images, and video are posted to the social web to gain exposure and because these stories just need to be told.

Gladwell notes that “this is not a top-10 list, nor are these listed in any particular order. It’s also incomplete.” Please contribute to the conversation by posting a comment to his article and use #10ways in your tweets.

I highlight SalaamGarage because founder Amanda Kostner presented a keynote in our most recent Web 2.0 Expo San Francisco, which you can view here.
