Online community Study Guide

📖 Core Concepts Online Community – A group of people who interact via computer‑mediated communication, sharing common interests or goals and guided by platform‑specific norms. Core Characteristics – Shared communication space, ongoing relationships, sense of belonging, identifiable identity, and a common purpose that persists over time. Membership Life‑Cycle (Kim) – Visitor → Lurker (observes) → Novice → Regular → Leader → Elder (gradual disengagement). Key Roles – Architect (designs purpose & structure), Manager (enforces rules, welcomes newcomers), Power User (drives discussion), Professional Member (paid contributor). Types of Communities – Blogs/microblogs, Internet forums, social networking sites, gaming communities, professional/niche networks. Technology Acceptance Model (TAM) – Self‑efficacy → perceived ease of use → perceived usefulness → actual participation. Intrinsic motivation boosts all three. Growth Dynamics – Slow start → virtuous cycle (more members → more contributions → still more members). Modeled by the Bass diffusion curve. Participation Distribution – 1 % rule (≈1 % create content), expanded to 1‑9‑90 rule (1 % post, 9 % comment/share, 90 % lurk). Risk & Trust – Harassment, misinformation, privacy leakage, identity deception; trust built through knowledge‑based and foundation‑based cues. --- 📌 Must Remember Definition – “Online community = people + shared interest + mediated communication.” Three Success Pillars – Belonging, identity, interest. TAM Predictors – Self‑efficacy, perceived ease of use, perceived usefulness → higher participation. Bass Diffusion Formula (simplified): $$A(t)=p+(q \cdot \frac{N(t)}{M})$$ where p = coefficient of innovation, q = coefficient of imitation, N(t) = adopters at time t, M = market potential. Membership Phases – Lurker → Novice → Regular → Leader → Elder. Roles & Powers – Moderators enforce rules; administrators control technical maintenance; power users shape norms informally. 1‑9‑90 Rule – Expect 90 % of users to only view content; plan retention strategies accordingly. Motivation Theories – Reciprocation, Consistency, Social Validation. Common Risks – Toxicity, cyberbullying, privacy traces, misinformation (especially health). --- 🔄 Key Processes Community Planning Define purpose & target audience → design architecture → set netiquette. Recruitment Interpersonal: personal invites → high fit. Word‑of‑mouth: members recommend → organic growth. Impersonal: ads → broad reach, lower fit. Onboarding (Socialization) Create introductory thread → assign “older‑timer” mentor → provide clear documentation. Retention Loop Friendly interaction → sense of belonging → repeat contribution → higher activity → attracts more members. Growth Monitoring Track active‑user ratio (1‑9‑90), moderator workload, toxicity signals → adjust barriers or incentives. Risk Management Implement moderation policies → privacy settings → verification (screening) for high‑risk spaces. --- 🔍 Key Comparisons Forum vs. Blog – Forum: threaded, multi‑user discussion, roles (moderator, admin). Blog: author‑centric long‑form, comments optional, limited editing by others. Lurker vs. Power User – Lurker: consumes only, still gains information, low visibility. Power User: initiates threads, provides feedback, informal leadership. Self‑Sustained vs. Dependent Community – Self‑Sustained: relationships form entirely online; identity built within the space. Dependent: extensions of offline friendships; offline identity dominates. Open‑Source Project Community vs. Casual Discussion Forum – Open‑Source: stricter entry (code reviews, contributor agreements). Casual Forum: lower barriers, higher churn, more tolerant of off‑topic posts. --- ⚠️ Common Misunderstandings “All members are active contributors.” → 90 % usually only view. “Anonymity guarantees safety.” → Enables harassment, identity deception, and misinformation. “More members automatically improve quality.” → Without proper netiquette and moderation, growth can dilute signal‑to‑noise. “Moderation is optional.” → Essential for managing toxicity and preserving trust. “A single platform fits all needs.” → Different goals (e.g., rapid updates vs. deep discussion) require distinct tools. --- 🧠 Mental Models / Intuition Garden Analogy – A community is a garden; you must plant (recruit), water (engage), weede (moderate toxicity), and harvest (recognize leaders). Network Effect Loop – More users → more content → higher perceived value → attracts even more users. Barrier‑Reward Balance – Higher entry barriers filter for commitment but can also limit diversity; find the sweet spot for your purpose. --- 🚩 Exceptions & Edge Cases Gaming Communities – Tolerate higher levels of “trash talk”; moderation focuses on cheating rather than language. Professional Health Forums – Stricter verification, higher liability for misinformation. COVID‑19 Spike – Sudden surge in health‑related participation; usual moderation capacity may be overwhelmed. Legal Constraints – Copyright concerns can limit collaborative content creation in certain jurisdictions. --- 📍 When to Use Which Choose a Forum when you need threaded, searchable discussions and multiple user roles. Choose a Blog/Microblog for broadcast‑style updates, thought leadership, or short‑form announcements. Choose a Social Network for personal profile building and rapid friend‑type connections. Deploy a Gaming Platform if the primary activity is real‑time cooperation or competition. Apply the 1‑9‑90 Rule to set realistic expectations for content generation and allocate moderator resources accordingly. --- 👀 Patterns to Recognize Sharp drop in new‑member posts → possible onboarding failure. Spike in moderator deletions → emerging toxicity or rule violations. Consistent 1 % posting rate → healthy but may signal stagnation if overall traffic is low. Repeated “help‑request” threads → need better documentation or FAQ. High “likes” on controversial posts → potential polarization; monitor for cyberbullying. --- 🗂️ Exam Traps Distractor: “Anonymity eliminates all privacy concerns.” → Wrong; activity is still traceable by platform operators. Distractor: “The 1 % rule means only 1 % of members matter.” → Misleading; lurkers still contribute to traffic and community perception. Distractor: “More moderators always improve community quality.” → Over‑moderation can suppress authentic interaction. Distractor: “Growth is linear once a community passes the ‘critical mass’ point.” → Growth follows a Bass diffusion curve, not a straight line. Distractor: “All online communities require the same netiquette.” → Netiquette varies by community type (e.g., gaming vs. professional health).
