The technique is one promise, a few formats, one slot: a stranger understands what the account is for from any single post. How it works: write the account's promise in one line; every post keeps it, in two or three repeatable formats, at one fixed time in the audience's evening. It is right for: running an account as a series. On one measured account the median of the ten posts after a change of promise was 33.6 times the ten before; the formats had not changed. A step wears off: the median fell to about a quarter between the first and the second half of October, as the examples began to repeat. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing."
