@davew: Blogs are little things
Blogs can be ephemeral.
Lots of people made arbitrary rules about blogging. You need to update your blog daily. Blog posts should be structured essays.
None of these rules are real. Many of these rules were made up by marketers and professional content creators and may be true in those fields, but if you are not a marketer, or looking to generate direct income from your blog, those rules do not apply to you.
