Don't Trade Short-Term Social-Media Success for Long-Term Donor Value

A new social-media tool, Jumo.com, is seeking to provide a platform that builds stronger connections between supporters and the causes they support.

It’s a place where you can find issues and projects that interest you, follow them to get updates, and then support them if you like.
