Update (11 months later): This post may contain some outdated advice. The main advice that is applicable to the average blogger is that you should have a post frequency. That’s all. As for the rest of the advice, follow with caution.
Why is it such a big deal in blogging and writing?
Anybody’s guess. It’s because in blogs, people expect you to have a regular posting schedule. They don’t want to be forced upon two posts on the same day, but they also don’t want to wait a whole month for a single post.
I’ll admit it.
I suffer from inconsistency too.
