Provide more information on campaign pages
I think it would be a good idea to provide more information, or at least links to more information on the campaign pages so people have more of an idea what its about.
The example at the moment is the government snooping campaign page. Someone looking at this page might think "government snooping, that sounds bad, I'll sign that" or if they are more like me they might have questions about exactly what it is they are being asked to object to. eg. What is the proposed legislation? What are the consequences of it likely to be? What stage is the legislation at? Sometimes with 38 degrees and other campaign sites it feels like people are being given a dumbed down version of what's going on. Obviously you have to find a balance between giving people enough information to support the campaign and going into too much detail, but maybe its worth a bit more thought.
