This interview with Manik Rathee gives a really interesting perspective of the online campaign in the Obama camp. The interview reveals that not only did the work done for the campaign get a huge amount of exposure but it also provided an extremely satisfying end result (though I'm sure the team's Republican counterpart wasn't so thrilled).
So, have a read and discuss: what's the most enjoyable part of a project to you? Creating? Innovating? The end result? Seeing people's reactions? Seeing people using what you've made? (There are so many things to enjoy!)
