A couple of weeks ago, I wrote about the amount of time writers can spend working without actually creating any new material. This week I will refer you to Should You Focus on Your Writing or Your Platform? by Jane Friedman, which was posted at Writer Unboxed. She writes about something similar, specifically the time writers are now spending on platform, which is a form of marketing. Marketing has become a huge time suck for writers, and Friedman has some suggestions about how to decide when to focus upon it.
To get you interested, Friedman says, "...we now live inside an unending media conversation wheel, where anyone can find a niche readership, do solid work on building a platform, and even put writing on the backburner—and still reasonably claim to be a writer."
