I think job boards are seeing a similar fate as some of the traditional print media. As time goes by, some of the social media is taking precedence over things like job boards. And job boards are changing as well. You've got BeKnown, a Facebook application for professional networking, which is essentially a product from Monster, the job board.

The industry that supports organisations recruiting and finding people is changing and adapting to reflect the online world that we're now increasingly spending our time in. I think the last time I did a print advertisement in a newspaper was probably in 2002.

I hope to have a long relationship with technologies and companies that enable us to connect with people that want to come and work with Walmart. So I'll say the same with LinkedIn as with other social media: I hope to be able to continue to leverage ways that help us make connections with candidates and people who are interested in Walmart.

With LinkedIn, I hope it continues to be a professional networking site. I spend as much time using LinkedIn to network through and talk to likeminded professionals, as I do actually recruiting, and I think LinkedIn is a great source for talking to experts in whatever industry you're in, whether it be retail or human resources or finance. There're discussion groups and meeting places for people to get together and share ideas and stories and challenges and problems.
