I think LinkedIn is a lot more than a job site. It's a professional networking area that helps connect likeminded people. Twitter has a different approach in terms of those short byte stories, things that are going on that're affecting people. It allows you to sometimes follow professionals or other groups of people that you're interested in. I think such things will continue to flourish and grow.

It certainly helps us find people to talk to. And then our processes and assessment methodologies help to take care of the rest of the recruitment and hiring process.

I don't think social media can help me qualify whether someone's a good cultural fit for Walmart or whether there're capabilities that enable them to do a great job for Walmart. We still need to rely on interviews and assessments and testing and different things that we do once we've started conversations with people. I don't think that will change. I'd love it if it could. I'd love it if there's something that could tell you whether people are going to be successful, but I think that probably gets into a whole new world of technology and could be quite scary.
