What you can learn from James Cameron and Avatar. With Avatar recently becoming the highest-grossing movie of all time, Hollywood is looking to learn what it can from the mystical blue people of the Na'vi.

Finance blog, BloggingStocks, has an interesting post about the business lessons entrepreneurs can learn from James Cameron. In their words, "Cameron is a New Age entrepreneur--that is, combining creativity, unconventional wisdom, over-the-top optimism and good business sense."

Employing new social media features to boost sales. Several social media sites are expanding efforts to help small businesses manage customer relationships, reports TheStreet. Twitter, for example, allows entrepreneurs to create a series of lists that will allow you to follow specific Twitter handles, such as your competition or potential new clients.
