This is really interesting article following the ways in which Lady Gaga has capitalized on using social media to promote her brand - especially now that she has her own social networking site for her fans that launched earlier this summer. I don't consider myself an avid fan of hers, but I'm really impressed with the way she uses social media to interact and connect with her fans; which is basically the only reason why I follow her on Twitter.
