Break it Up
Yesterday I warned you about blog posts that are too long for your hurried readers. How do you avoid posts that are time-consuming to read quickly?
First, just write without regard to length. Say what you have to say. But then really look at your writing with a critical editor's eye and notice where you can split the writing into two or more sequential blog posts. This critical eye will get you a week's worth of posts and return visitors in one writing session! With a little practice, you'll see how the mind naturally links related chunks of information that can easily be broken into segments and published over the course of a week.
I know many bloggers who write their blog posts over the weekend using exactly this approach and you can, too.
