Lurker

Lurker is a 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 Lurker rather than just read about it. In short: In Internet culture, a lurker is typically a member of an online community who observes, but does not participate by posting or commenting. The exact definition depends on context.

Key takeaways

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

Reference excerpt

In Internet culture, a lurker is typically a member of an online community who observes, but does not participate by posting or commenting. The exact definition depends on context. Lurkers make up a large proportion of all users in online communities. Lurking allows users to learn the conventions of an online community before they participate, improving their socialization when they eventually "de-lurk". However, a lack of social contact while lurking sometimes causes loneliness or apathy among lurkers. Lurkers are referred to using many names, including browsers, read-only participants, non-public participants, legitimate peripheral participants, vicarious learners, or sleepers.

History Since the beginning of computer-mediated communication lurking has been a concern for community members. The term "lurk" can be traced back to when it was first used during the 14th century. The word referred to someone who would hide in concealment, often for an evil purpose. In the mid-1980s, the word started to be applied to the Internet when bulletin board systems became popular. The bulletin boards were accessed through a single phone line that users would call to upload files and post comments to share with the community. It was expected that those using the system and consuming resources would contribute. Because lurkers would keep the phone line busy for extended periods of time without contributing anything, they were often viewed negatively and would be barred by the system operator who managed the BBS. Today, lurkers are viewed both positively and negatively. In many communities lurkers are still seen as free-riders. They are perceived as a drain on the public goods since they "take without giving back." However, some communities encourage newbies to lurk. By lurking, newbies can learn more about the culture of the community, understand the community's social norms, and become familiar with the key members of the community. Lurkers are also viewed positively in present-day communities because they provide an audience for the mass media. The presence of lurkers is often the justification for receiving advertising support. Lurkers are often hard to track in computer-mediated communities. Because they are not posting and mostly just read content, they leave behind few traces that can be tracked. In open source project communities, it is estimated that at any point in time, 50% to 90% of the community may be lurkers. Depending on the community, this may be consistent with the 90-9-1 principle.

Rationale Lurkers lurk rather than participate for a variety of reasons. A majority of lurkers profess that they lurk simply because they think that browsing is enough for them. Users also choose to lurk in order to find examples to follow when they decide to participate, avoid making redundant posts or contributions, and learn more about the topics of conversation. A lurker's need to learn about the community before contributing also explains why almost twice as many users lurk on technical support communities where more information is required to post as compared to health support communities. Researchers have shown that different motivations underlie reading, contributing, and moderating web forums. Pure lurkers more often are motivated by the fact that the community is the only place to find a certain kind of content, while moderators and contributors are motivated by either duty or feelings of attachment. Lurking on social media can also be a form of receptive reading, whereby users seek to understand the opinions of those with a divergent point of view. In much of the published literature, "lurking" is treated as a personal trait. However, concepts of legitimate peripheral participation and "de-lurking" suggest that lurking may be more situational than dispositional. In a study of online communities in which it was possible to see the total membership list, researchers were able to count the number of members who were public participants in one community while remaining silent or non-public participants in another community. 84% of the members fit this mixed pattern, indicating that people choose whether to lurk or to contribute on a per-community basis.

Potential benefits

Lurker benefits Lurking behavior provides some benefits to users. Mo and Coulson found that lurkers on an online support group for HIV/AIDS did not differ from posters in their levels of care, self-efficacy, optimism, depression, and loneliness. They also found that lurkers felt more energetic than posters. In a study that addressed lurking in E-learning, scholars found evidence that lurking is a helpful type of participation in online courses. Students said that the most common reasons they lurked before posting were to discover a message to reply to, to identify a model to adopt, to bypass providing a similar reply, and to acquire knowledge regarding the topic. Students in this study also expressed that they came back to read posts on online course discussion boards in order to check whether others had responded to their posts or to review a previous concept.

Worked examples

Example 1 — a first encounter with Lurker

Start with the simplest possible case. Write down what Lurker claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Lurker 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 Lurker 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 Lurker

In research
Lurker appears in 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 Lurker 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
Lurker is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s neologisms, Internet culture, so understanding it makes those chapters shorter.
In everyday life
Look for Lurker 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.

Frequently asked questions

What is Lurker in simple terms?

In Internet culture, a lurker is typically a member of an online community who observes, but does not participate by posting or commenting. The exact definition depends on context.

Why does Lurker matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lurker?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
