I'd love to hear from site visitors as to why they blog. I gave a talk last year at our regional SCBWI conference and will be giving it again in April. I titled the talk, "Websites, Blogs, and Platform Building."
When it comes to writers, I do feel that every published and yet-to-be-published writer should have a website and/or a blog. They are a means to an end: building your platform. It's your platform that editors and agents look for once they fall in love with your writing...and even before! The workshop i give covers what you need to know in order to launch your own website and/or blog in a cost-effective manner. It covers the terminology, software, costs, philosophy, design components, etiquette, and maintenance of good sites that inspire visitors to bookmark them and come back to them time and again. Sometime in the future I may put this info in an eBook. I'll let you know when I do.
Now the above is for writers...but who else blogs? and why? I'd love to hear from you! Tell me why you blog. Do you have more than one blog? What topics are you blogging on? Fun stuff, huh?
