The main point Kristen makes is this: Blogs strictly devoted to the how-tos of writing gain and maintain a limited audience. So reach out to folks who share your interests, by blogging on subjects all of you care about--and then toss-in some posts about the trials & tribulations about writing life.
Speaking of trials & tribulations: I'm half why through Kristen's book, "WANA," as she abbreviates it and am learning a lot. Like the mistakes I've made, from a writer's point of view, setting up this blog. But that's the subject of another blog post...
I'm a retired USAF TACP (Tactical Air Control Party) member, now working for Washington State Emergency Management. In addition to being an Emergency Operations Specialist at my day/night/weekend job, I'm a Foreign Affairs Specialist, gamer and writer.
I maintain three blogs as an on-line platform. "Stern Rake Studio," my central site, explores a variety of topics on gaming, pop-culture and writing. "Station WTFO" is where I post comments and discussions on the national and international issues that concern us. Finally, "The Redshift Chronicles," is a spin-off of "Stern Rake Studio." This site focuses on sci-fi gaming and is home to my long-form webcomic "Breakout from Bongolaan."
