EchoDitto clients 1Sky, Global Zero, and Brighter Planet are featured in a short list of outstanding advocacy sites:

"A couple of weeks ago I asked a group of online advocacy professionals to suggest a few good issue-based campaign websites, and the results provide an excellent snapshot of the current standards in the field. Particularly since an e.politics article from 2006 listing some then-outstanding advocacy sites still generates a healthy amount of Google traffic, it’s clearly a topic that could use some updating."
