Social media allows you to find, engage with, and develop potential fans, customers and clients - not pitch them a product cold.
What does that mean for artists? Stop sending out tweets like "Buy our album!" or "Check out our merchandise!" or "Give us money for a new van!"
Instead, develop relationships first, drive them to your site and convert them into buyers or contributors there. People expect to spend money on websites, but trying to pitch them in a social media context will only leave a sour taste in their mouths.
