Books on Platform Design: What Students Should Read About the New Social Networks

Hook: What to read when platforms change the rules

If you're teaching or studying media or computer science in 2026, you face a familiar frustration: course readers lag behind the platforms shaping public life. Students need texts that explain not just how social networks work, but why design choices—algorithms, moderation systems, and business incentives—produce real-world harms and opportunities. This guide gives a curated reading list and practical classroom tools focused on platform design, algorithms, and community moderation—with case studies from emergent networks like Digg and Bluesky to ground theory in contemporary practice.

Why these books matter in 2026

Late 2025 and early 2026 brought fresh evidence that platform design decisions ripple quickly. Bluesky introduced features like cashtags and LIVE badges amid a downloads surge linked to controversy on competing networks; Appfigures and TechCrunch reported daily installs jumping nearly 50% as users defected from a platform facing an AI-deepfake scandal (TechCrunch, Jan 2026). Meanwhile Digg re-entered public conversation with a paywall-free beta that positions it as a modern Reddit competitor (ZDNet, Jan 2026). These shifts are perfect case studies for courses: they show how governance, product features, and economic models shape user behavior and public outcomes.

Quick case note

"Bluesky saw daily downloads jump nearly 50% after a competitor's content-moderation crisis in early 2026." — market data summarized in TechCrunch, Jan 2026

Use these episodes to teach students to link technology, incentives, and policy—exactly what the best platform design books do.

Core themes for a platform-design module

• Algorithmic ranking and architecture: How recommender systems and feed algorithms prioritize content and shape attention.
• Community moderation and governance: Between automated takedowns and human councils, how do platforms define acceptable speech?
• Economies and incentives: Attention markets, ad models, subscription paywalls, and new token/creator economies.
• Design ethics and values: Trade-offs between engagement, safety, and public good.
• Emerging network case studies: What the revivals and pivots of sites like Digg and Bluesky reveal about resilience and design choice.

Curated reading list: Books every student should read

Below, each pick includes: why it matters for media and CS courses, a suggested short assignment, and 2–3 discussion questions instructors can drop into class.

1. Foundational: "The Platform Society" (edited volume)

Why include it: Offers interdisciplinary perspectives—legal, sociological, economic—necessary for taking a systems view in courses that combine media studies and computer science.

Assignment: Short comparative essay: pick two chapters and relate them to a recent platform change (e.g., Bluesky adding cashtags).

Discussion prompts: How do legal frameworks shape design choices? Can platform architecture substitute for governance?

2. Algorithms & recommender systems: "Algorithms of Oppression" (updated edition)

Why include it: Newer editions (post-2023) address recommender systems and bias in social feeds—essential reading for students building or auditing algorithms.

Assignment: Audit exercise: pick a trending post on a social feed and reverse-engineer factors likely boosting it.

Discussion prompts: Where do biases enter training data? Which design choices could mitigate amplification of harmful content?

3. Moderation & governance: "Custodians of the Internet" (or similar)

Why include it: Focuses on the human systems—content moderators, policy teams, appeals processes—and how they interact with automation.

Assignment: Design a three-tier moderation workflow for a hypothetical new network (auto-filter, community review, appeals board).

Discussion prompts: What is the right balance between automation and human oversight? How should small startups afford moderation at scale?

4. Economies and business models: "Attention Machines" (or a recent economics of platforms text)

Why include it: Breaks down ad-driven attention economies, subscriptions, and creator payments—key to understanding why Digg removing paywalls matters.

Assignment: Modeling exercise: simulate quarterly revenue under ad vs. subscription vs. hybrid models for a 1M-user platform.

Discussion prompts: How do monetization choices influence moderation? Can alternative economies produce healthier networks?

5. Case studies & emergent platforms: "Reviving the Feed"—a contemporary anthology

Why include it: Includes fresh chapters on Digg's 2026 beta and Bluesky's feature pivots. Valuable for students who must connect theory to real product decisions.

Assignment: Case brief: analyze Digg's paywall removal—what user groups benefit, what revenue risks emerge?

Discussion prompts: When does openness (no paywall) spur growth vs. creating sustainability challenges?

6. Practical textbook: "Designing Social Interfaces" (modern edition)

Why include it: Offers concrete UX patterns and engineering trade-offs for social features (feeds, likes, reposts). Great for CS labs.

Assignment: Build a minimal feed prototype with two ranking strategies (recency vs. engagement) and compare outcomes.

Discussion prompts: What UX nudges unintentionally encourage harassment or misinformation?

How to integrate the list into a semester (practical syllabus)

Below is a four-week module that fits into a standard 14-week course or a short-term seminar. Each week mixes theory, case study, and a hands-on activity.

1. Week 1: Architecture & Algorithms
   • Read: Selected chapters from "Algorithms of Oppression" and "Designing Social Interfaces"
   • Activity: Reverse-engineer ranking factors for two sample feeds
   • Outcome: Short memo describing algorithmic trade-offs (use the privacy-first personalization playbook to discuss on-device trade-offs)
2. Week 2: Moderation Systems
   • Read: "Custodians of the Internet" chapters + a current piece on Bluesky's moderation approach
   • Activity: Draft a three-tier moderation policy for a new social network
   • Outcome: Policy document + class role-play appeals board
3. Week 3: Platform Economies
   • Read: "Attention Machines" chapters + Digg beta coverage
   • Activity: Build simple financial model comparing ad vs. subscription revenue
   • Outcome: Presentation on sustainability and user incentives (see monetization notes in the creator cashflow playbook)
4. Week 4: Capstone Case Study
   • Read: Case chapters on Digg and Bluesky
   • Activity: Team project—create a launch plan for a new feed feature with moderation, ranking, and revenue strategy
   • Outcome: Pitch deck and technical spec (include a multi-cloud failover note from the multi-cloud failover patterns review)

Classroom-ready discussion questions and prompts

• Compare two models for content ranking: engagement-first vs. civility-first. What metrics would you use to evaluate success?
• How should a small platform prioritize moderation when budget is limited? What community-driven solutions scale?
• Evaluate the trade-offs of removing a paywall (Digg's 2026 move). Who gains, who pays, and what governance challenges follow?
• Discuss Bluesky's product choices (cashtags, LIVE badges): how do niche features change network effects and moderation needs?

Assignments and project ideas that scale for CS & media courses

• Feed simulator: Implement two ranking algorithms and analyze which content types dominate each.
• Moderation policy lab: Create and test a community moderation rubric; simulate appeals and outcomes.
• Business design sprint: Build a 6-month go-to-market for a niche social app, including revenue and moderation plans.
• Ethics code review: Audit a real platform's policies and recommend changes grounded in course readings (pair with the zero-trust approach to data flows).

Assessment rubrics — what to grade for

• Clarity of argument (30%): Are claims supported by readings, data, or code?
• Design feasibility (25%): Could the proposed feature or policy be implemented at scale? (Consider engineering notes from the modern observability guide.)
• Ethical reflection (25%): Do students identify downstream harms and mitigation strategies?
• Collaboration & communication (20%): Quality of presentations, docs, and team coordination.

Supplementary readings and up-to-date resources (2026 picks)

Keep a rolling list of short, current readings to pair with the books. In 2026 include:

• TechCrunch coverage of Bluesky's feature rollouts and Appfigures install data (Jan 2026)
• ZDNet reporting on Digg's public beta and paywall changes (Jan 2026)
• Recent policy whitepapers from civil-society groups on AI moderation and deepfakes (2025–2026)
• Preprints on recommender-system fairness from leading ML conferences (2024–2026) and practical notes from the privacy-first personalization playbook

Practical advice for instructors

• Mix long-form and short pieces. Use books for theory and recent articles for contemporary relevance—students need both.
• Bring product artifacts into class. Screenshots, feature changelogs, and App Store metrics foster concrete analysis.
• Invite guest speakers. Moderators, product managers, or policy researchers from emergent networks make lessons real.
• Use lightweight labs. A one-week feed prototype or a moderation rubric workshop teaches engineering and ethical fluency.
• Emphasize reproducibility. When assigning audits, require students to include data sources and methods (see notes on observability in modern observability).

Building a book club or reading group around platform design

Many students learn best through conversation. Here’s a ready-made monthly pick and meeting kit:

1. Month 1: "Algorithms of Oppression" — focus: algorithmic bias
2. Month 2: "Custodians of the Internet" — focus: moderation labor
3. Month 3: "Attention Machines" — focus: economics

Meeting kit (90 minutes):

• 0–10 mins: warm-up—each participant shares one surprising takeaway
• 10–35 mins: breakout groups—each group addresses one discussion prompt
• 35–60 mins: case time—analyze a 2026 event (e.g., Bluesky downloads surge) through the lens of the book
• 60–80 mins: practical brainstorm—small teams propose a feature or policy change
• 80–90 mins: wrap-up and readings for next month

Final notes: What students should be able to do by the end of the module

• Explain how algorithmic ranking shapes attention and outcomes.
• Design a feasible moderation workflow that balances automation and human judgment.
• Model how monetization choices affect platform behavior and governance.
• Write a short policy brief that translates technical details into actionable recommendations for product teams or regulators.

Closing — reading for real-world impact

Platform design is no longer an abstract discipline relegated to specialists. Between Bluesky’s feature pivots and Digg’s public relaunch in 2026, the politics of platform choices are unfolding in real time. The books and exercises above help students make sense of those changes—and prepare them to design safer, fairer networks.

Actionable takeaway: Start a four-week module this term: pair one of the books above with two recent articles, run the feed-simulator lab, and end with a student policy brief. You’ll give students conceptual depth and practical experience in equal measure.
