Platform term. Also written threads, tweet thread.

Where it comes from

Threading began as a workaround: X capped posts at 140 and then 280 characters, so people chained replies to their own posts to write at length. The platform later formalised it. Meta then launched a separate app called Threads in 2023, which is a different thing entirely and a permanent source of confusion.

How it is actually used

A thread is signalled with a numbering convention (1/, 2/) or the 🧵 emoji, and the first post carries all the weight — it is the only one most people see, and the only one the algorithm judges. The format has a poor reputation because it is heavily used for engagement farming, where a promised thread delivers padding. A thread earns its form when the parts are genuinely sequential rather than a list broken up for effect.

Examples

  • "a thread on why this keeps happening 🧵"
  • "great thread, saving this"
  • "this could have been one post"

Can a brand use it? Safe for brands

Safe. The reputational risk is writing a thread that did not need to be one — the "this could have been one post" reply is common and deserved.

Frequently Asked Questions

What is a thread on social media?

A series of connected posts by the same person, read in sequence. It exists because character limits made long-form writing impossible in a single post.

Is Threads the same as a thread?

No, and the collision is unfortunate. Threads is Meta’s text-based platform launched in 2023 and linked to Instagram. A thread is a chain of posts, most associated with X.

How do you write a good thread?

Make the first post work alone, because it is the only one most people will see. Then make sure the parts are genuinely sequential — if the order does not matter, it should have been one post or an article.
