Here are some quotes to ponder from that article:
One of Goodreads' best interactive tools are featured author groups, he said, where authors make themselves available to answer readers' questions on the site for a number of days.Okay, setting aside, Twitter, Facebook, and Goodreads Author Sites, what are you doing that you can see is affecting your sales? I think blogging could be added to the list.
Looking to the future, Joel [president of Twist Image] pointed to figures that showed sales of smartphones outpacing PCs in the fourth quarter of 2010. "This is the shift away from fixed locations. This is the shift where we're going to have a society that is much more in tune with using our mobile devices as their primary form of connectivity," he predicted.
Then [Joel] described a SnapTell app's ability to recognize a photo of a book and provide the user with information about the book, including the nearest bookstores and how many copies are in stock.
Joel … said many companies that consult his digital agency now blog and tweet and have Facebook pages, but that is not enough.
