How do these live tools help with politics?
This question was just asked a few minutes ago and the main answer I've heard is that it helps with knowing what people's reactions are. It also helps with having a purer interaction with the politicians and others. Real time interactions with politicians is great and helpful because then the message is not filtered or altered by others. You get to see the real person behind the politics.
I think that this is a great advantage, but I don't believe that most people would be able to use it first hand. They would have to wait for it to be published somewhere. Now would that amount of time before it's publication change that "real person" view?
