Market Research on LinkedIn

One of the latest features to be added to LinkedIn is a survey feature for market researchers to use. As reported here, Dan Shapero, Director of Business Services from LinkedIn, had this to say:

‘LinkedIn overcomes quality and authenticity issues that other sample providers face. Because of the public and self-policing nature of LinkedIn, members provide deep and accurate profile information and they update that information constantly.’

What are your thoughts? Have you seen the new survey feature, and/or do you think it will prove useful?
