Well, there should be a caveat to that--and I speak as a volunteer for their Off The Bus project. Sometimes the effort of getting direct information out is more important than pay and making public the on-the-ground voting situation was more important to me than getting paid for it.
The bigger the pay wall, the dumber the voting public is going to be because they're not going to see information essential for making good choices. For that reason I was also an unpaid contributor to MSNBC's Vine before they shut that down.
