A most effective method to get attention for your work (and sales for your published books) is to establish an online presence. The modern art form called by the unfortunate name of blog is well-suited for this purpose.
But, because it's so deceptively easy, writers need to be on guard!
A writer's blog should never be boring, because there's a good chance if the blog posts are dull, the book will be too. Or at least people will think so.
Scary thought, isn't it? A little too much pressure?
The writer blogs for a variety of reasons--to connect with others in the business, or reach the book's demographic, or to establish a platform and online presence. Or maybe just for fun.
Whatever reason, it's a career move for the writer whether he realizes it or not. A writer--a storyteller-- is an entertainer. So one who blogs had better be entertaining, interesting, thoughtful, wise, informative, or some combination of fascinating.
And please choose your words with care. Because people are watching. Or reading. You hope.
A writer can be many things online but never dull. Better to be absent than dull. Take plenty of time to think about your posts, to edit them as you would a published work before you click that much too easy publish button.
Your career may depend on it.
