Burstiness in a blog post

The metronome rhythm of an AI-written blog post — why every sentence ends up the same length, and what changes when you put one short one in.

BurstinessBlog postWritten by the desk

Read three paragraphs of an unedited AI-written blog post and you'll notice the cadence before you notice the content. Every sentence is between sixteen and twenty-two words. Every paragraph has three sentences. The piece moves with the same metronome from start to finish, and it puts the reader to sleep at exactly the same rate per paragraph.

Bursty prose has a rhythm you can hear

Good blog writers vary sentence length deliberately, not at random. A long, careful sentence that sets up an idea. Then a short one that lands it. A medium paragraph that develops the example. Then four words of judgement. The reader's attention rises and falls — and stays.

Before

Many companies struggle with documentation because their engineers find it boring to write. This results in outdated documents and frustrated users who cannot find the information they need. The solution requires a cultural shift where documentation is valued as much as the code itself.

After

Most documentation is bad because the people who could write it are bored. That is the whole problem. The fix is rarely the new platform we keep being sold — it's making the writing job small enough that a tired engineer at 4pm will actually do it. Two paragraphs, one example, ship.

The rewrite has sentence lengths of 14, 5, 32 and 6 words. The original has 17, 17 and 19. The information is similar; the rhythm is what changed.

The two-sentence test

Pick any paragraph of your draft. Add one sentence under six words and one sentence over thirty. Don't add information — just rephrase. Read it back. The whole paragraph will feel more written almost immediately.
