Tell your audience what your blog posts are about as early as possible (marginalia.nu)

To avoid distracting the reader from your message, you should probably remove or change the location of low-value information in your webpage templates, such as the date you published your writing, a repetition of the title, a reminder that your writing is in a folder called "Weblog" on your website, and tags linking similar writings on your website. (What were you trying to tell me your post was about again?)

Have schools stopped teaching the standard essay formula?

Summarize your essay in the first paragraph (tell what you're about to say), then actually say it, then end by summarizing what you just said.
