A permanent and regularly updated Nonprofits on Twitter list can be found under “LISTS” in this site’s top navigation.
We here at Top Nonprofits have recently published a list of the top 50 of these nonprofits based on total twitter followers. The permanent version of this list will be updated at least once a month to reflect current rankings. To get updates on this list be sure to subscribe to our email list as well as Follow @vankorlaar
We’ve even added follow buttons allowing you to follow them right from the Top Nonprofits on Twitter List.
