Ever since my publisher told me I should start a newsletter, I have been trying to figure out how it would be different from a blog. I know how to blog. I maintained a content strategy / technical communication blog for years. It did a lot for my content strategy career, it helped launch my two content strategy books, and it still attracts hundreds of views a week despite my not having posted anything there in a few years. It had a pretty decent roster of followers. When I switched to fiction, I thought I would just do the same thing for my fiction career with this blog. But my publisher says newsletters are what sells books, which is why there is a newsletter signup form right next to the blog subscription form in the sidebar and footer of this page. (Please do sign up to either or both!)
So now I have to figure out if what I learned about blogging applies to newsletters, or if they are really just the same thing in different guises.
