Why? Why do you need to make those distinctions? The doctor couldn't fly to Haiti if he hadn't been funded. You need a lot of different pieces working together to make big change.
But someone who posted "Like this if you love Doctors in Haiti" did very little, just as people signing up for a website do very little. I don't like to belittle "raising awareness" campaigns because I know how important they are. But there is no substitute for getting your feet on the ground or your money from your wallet. I worry that we are creating a generation of people who think posting something in their facebook feed is saving the world. It’s certainly helpful, but it has to be in conjunction with real work.
People who aggravated against SOPA certainly did something -- an important thing -- but people who made hard decisions, called or emailed their representatives and really coordinated this effort did more.
This is a little different. For every person who felt they contributed to defeating SOPA, that's a person that politicians have to consider when enacting legislation. That's called paticipatory democracy, and it's pretty awesome!
