On the U2 album "Rattle And Hum" Bono introduces their cover of "Helter Skelter" with the line, "Charles Manson stole this song from The Beatles. We're stealing it back." Although not a direct correlation, there is the temptation to tell prospective clients "Social media sites stole your fans. We are going to help you steal them back."
Moving forward I think it will be important for bands (and businesses) to create walled gardens for their genuine fans. Yes, keep using social media, but don't give in to the idea that those sites are allowed to hold your fans hostage as they have been.
More importantly, show that better content, a better connection, and a better experience await the fan who steps outside of the app.
