One person over in the extremely active thread "What's the best way for writers to promote themselves" in Books and Writers Group on LinkedIn made the comment that she gets the most blog views when she posts pictures of her chickens...the problem, of course, is that people who come to view her chicken pictures are not necessarily the same people who might want to buy her books...which she acknowledges, btw...

And a common mistake too many writers make is that their blogs seem to be geared towards other writers rather than readers...if you write books about magic, for instance...your blog posts should be about magic...not writing about magic...make sense?

Unless you have an established fan base of readers, a blog about the content of your work is not going anywhere. So why not use it to network with other writers, maybe sell them a few copies and get them to recommend you to their friends?
