24 different accounts, no one of them more than twice. This is a subject people write about, not a subject one person owns.

What they have in common

11 of the 25 open with an observation, and 10 with a number. The mechanism the analysis names most often is specificity — exact numbers, named tools, precise dates — details that make a claim feel observed rather than asserted — in 17 of them; social proof in 3. 14 of the 25 put a figure in the first line. The median post is 251 characters long — a single post, not a thread.

Three to study

I’m moving $1B of my Square equity (~28% of my wealth) to #startsmall LLC to fund global COVID-19 relief. After we disarm this pandemic, the focus will shift to girl’s health and education, and UBI. It will operate transparently, all flows tracked here: https://t.co/hVkUczDQmz

Leads with a specific number, which is concrete enough to be worth a second of attention.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Written from experience rather than as advice, which is harder to argue with.

I cannot believe I am writing this.
— @geoffkeighley, 56,758 likes · open the post

Opens with a short, self-contained line that is easy to take in at a glance.
The opening line stands alone, so it reads completely before the post is expanded.
Written from experience rather than as advice, which is harder to argue with.

How to write one

Preserve the Hook → Landing structure and the leads with a number opening. Replace the subject matter entirely with the writer’s own product, story and numbers.
Preserve the Hook → Landing structure and the plain observation opening. Replace the subject matter entirely with the writer’s own product, story and numbers.
Keep the subject and change everything else: the facts, the figures and the voice have to be yours. What transfers is where the hook lands and how the second line earns it.
