Vagueposting

Vagueposting is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Vagueposting rather than just read about it. In short: Vagueposting, or vaguebooking, is the act of posting online cryptically without context or otherwise necessary information needed to understand the post. Intentions vary, with some vagueposting happening for the sake of engagement bait from people who have a fear of missing out, while other instances happen as a failure of transparent communication.

Key takeaways

Vagueposting belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Vagueposting to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Vagueposting from memory before moving on to harder problems.

Reference excerpt

Vagueposting, or vaguebooking, is the act of posting online cryptically without context or otherwise necessary information needed to understand the post. Intentions vary, with some vagueposting happening for the sake of engagement bait from people who have a fear of missing out, while other instances happen as a failure of transparent communication.

Definition Vagueposting is when an online user makes a post without context, causing other users to ask for more information. It is similar to a subtweet, which also refers to a vague post, albeit one made to specifically call someone out with plausible deniability, as well as rage-baiting, another engagement tactic which requires provoking other users for a response back. Zari Taylor, a researcher specializing in digital culture at New York University, argued that vagueposting was done for purposes of clickbait or controversy by prompting other users to interact with any given post, either to find clarity or interpret what it was about. One popular example of vagueposting, according to Rolling Stone and Fast Company, happened in 2026 when a user named Tamara made a comment on a TikTok video saying that she had bought 365 buttons, one for each day of the year, to keep her mindful about time. When other users asked follow-up questions about what she would do with the buttons, she responded, "Hey so it only has to make sense for me to do it and I don't feel like explaining it to anyone else."

History The term vaguebooking was originally coined to describe an intentionally vague Facebook post that prompted other users to follow up with the poster. While the term vagueposting dates back to 2011, usage exploded in the 2020s on Twitter and TikTok.

Worked examples

Example 1 — a first encounter with Vagueposting

Start with the simplest possible case. Write down what Vagueposting claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Vagueposting before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Vagueposting ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Vagueposting

In research: Vagueposting appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Vagueposting in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Vagueposting is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2011 neologisms, Culture of Facebook, Culture of TikTok, so understanding it makes those chapters shorter.
In everyday life: Look for Vagueposting outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
