Dave Carroll, a member of the Halifax band Sons of Maxwell, became famous for penning a song about a broken guitar after a negative experience he had with United Airlines.

That song, called United Breaks Guitars, had millions of hits on YouTube and made Carroll a sought-after spokesman about customer service.

As the CBC's Colleen Jones reports, Carroll has now launched a new social media network called Gripevine.com, aimed at helping to resolve consumer complaints.
