Not all writers respect all aspects of their own community. I've even read a novelist stating that bloggers are, by nature, a hobbyist. Bloggers similarly may see a book as only a side-line to sell from a blog, and a minor thing by comparison to a well-developed blog. Differing levels of respect shown for a book or a blog, depending if you see yourself as a book author or a blog creator. Of course, many of us respect both, or are both professional level blogger and author.
I have equal respect for my blogs as for my books. I don't trash either for money. Other's may do what they choose, I'll not judge, I just take a conservative approach. I'm after quality guest blogs that remain evergreen advertisements for an author's writing, rather than something that reads as an advertisement.
I won't allow a "Let's use the blog for one day book promotion," that has no building value for the blog. The big separator between the blogger and the author is that, I will not direct my reader off my website to email harvesting link sites, be it as a favour to authors, or for financial gain. Having thirty-thousand readers a week is a privilege I'll respect by ensuring I only add established and trusted outer links to the website/blogs.
These are my observations, feel welcome to disagree or comment.
Feel welcome to read more andcontact me if you feel we can work together with mutual respect for the blog and book form of our art.
