Question 1

What is federated social media?

Accepted Answer

A model where **many independently operated servers interconnect**, so users on different servers can follow and reply to each other — like email, where a Gmail user and an Outlook user communicate without either service owning the other.

**The contrast with centralised platforms.** On a conventional platform, one company owns the servers, the accounts, the rules and the ranking. Leaving means abandoning your followers and content entirely. Federation distributes those things across independent operators.

**How it works.** Servers — frequently called **instances** — run compatible software and exchange messages using a shared protocol.

**ActivityPub** is the main one, a W3C standard used by **Mastodon**, **PeerTube**, **Pixelfed** and others. Collectively this network is often called the **fediverse**.

**The AT Protocol**, used by **Bluesky**, takes a different approach with a stronger emphasis on **account portability** and on separating hosting, indexing and algorithmic feeds into distinct services that anyone can run.

**What federation gives you:**

**No single owner** who can change the rules, sell the company or shut it down for everyone.

**Choice of moderation.** Each server sets its own rules and can **defederate** from servers it considers harmful, so moderation happens at community scale rather than as one global policy.

**No advertising model by default**, which removes much of the incentive for engagement-maximising ranking.

**Chronological or self-chosen feeds** rather than an imposed algorithm.

**The genuine difficulties:**

**Choosing a server is a real barrier**, and it is the first thing a new user faces — an immediate decision with unclear consequences.

**Your experience depends on your server's** moderation, funding and reliability. A volunteer-run instance can close, and migration tools are imperfect — followers usually transfer, posts frequently do not.

**Moderation is uneven and under-resourced**, and consistency across thousands of operators is impossible by design.

**Discovery is harder** without a central index.

**Network effects**, which remain the decisive obstacle — a social network's value depends on who is on it.

**Costs fall on volunteers**, which is a real sustainability question.

Question 2

Can you take your followers with you when you leave a platform?

Accepted Answer

Generally no — and that asymmetry is the central economic fact of being a creator on someone else's platform. What you can usually export. Most large platforms provide a data download containing your

Question 3

What is the difference between a follower, a subscriber and a member?

Accepted Answer

Increasing levels of commitment and decreasing levels of platform control — and the distinction matters enormously to anyone building an audience, because the three are worth very different amounts.

Question 4

What is an engagement pod?

Accepted Answer

A group of accounts that agree to interact with each other's posts — liking, commenting and sharing on a reciprocal basis — in order to signal popularity to a platform's ranking system. How they

Question 5

How do social media algorithms decide what you see?

Accepted Answer

Every major platform now uses a ranking system rather than showing posts in chronological order. The system predicts how likely you are to engage with each candidate post, scores them, and shows you

Question 6

Who owns the photos and videos you post on social media?

Accepted Answer

You do. Posting does not transfer copyright. What you grant is a licence — permission for the platform to use your content in defined ways — and that licence is broad. What a typical licence says.

Question 7

What do influencer tiers like nano and micro actually mean?

Accepted Answer

Bands of follower count used by marketers to categorise creators — with no formal standard, so the boundaries differ between agencies, and the more useful finding is that the smaller tiers frequently
