The 50 nonprofits listed below are tackling some of the most important economic, social and political issues of our time. They are active in our communities, in our schools, and have valuable knowledge and experience that our nation’s elected officials could learn from and be inspired by, and yet very few U.S. politicians follow any nonprofits on Twitter. They mostly only follow other politicians. These sorts of echo chambers are common inside the Twitterverse – it’s the same with most celebrities and musicians who also tend to only follow each other, but in the case of nonprofits and politicians who are working on many of the same issues, not following the nonprofits listed below is a lost opportunity. Even if you don’t agree with the mission of a particular nonprofit, following them doesn’t need to signal an endorsement. Rather, it can simply demonstrate a tiny step towards better understanding the other side’s point view.
