Don't. ### What instance choice does affect 1. **The handle in your address.** `@you@mastodon.social` vs `@you@hachyderm.io`. 2. **The local timeline you see.** Every instance has a "local" feed of posts from that server. 3. **The moderation rules.** Some instances are stricter than others. 4. **Server uptime and stability.** Some instances are run professionally; some by hobbyists. 5. **First-impression signal.** Some instances signal "tech," some "politics," some "art." ### What instance choice doesn't affect 1. **Who you can follow.** Federation means you can follow accounts on any instance. 2. **Who can follow you.** Same — anyone on any instance can follow you. 3. **Discoverability.** Cross-instance discovery works the same regardless of where you're hosted. 4. **Content reach.** Federation handles distribution. ### Why account portability matters Mastodon supports account migration. If you sign up on `mastodon.social` and later want to move to `hachyderm.io`, you can — and your followers come with you. This means: pick something reasonable now. Don't agonize. You can always move. ### The "just pick one" answer If you're stuck: 1. **Generalist:** `mastodon.social` (the original; large and stable). 2. **Tech-focused:** `hachyderm.io` (run by Mastodon's CTO; tech-focused community). 3. **Indie/maker:** `indieweb.social` or similar small communities. Pick one. Spend 30 seconds. Move on. ## Lesson 2: Instance Themes and What They Signal Even though instance doesn't restrict who you can follow, your handle's instance signals something to others. ### Tech-themed instances Examples: `hachyderm.io`, `fosstodon.org`, `infosec.exchange`, `mastodon.online` **Signal:** "I'm in the tech world. Devs, engineers, open-source community." **Best for:** founders, developers, security, infra, anything technical. ### Generalist large instances Examples: `mastodon.social`, `mas.to` **Signal:** general-purpose. Doesn't lock you into a niche. **Best for:** newcomers who don't yet know their niche, or who span multiple niches. ### Topic-specific instances There are instances for: writers, photographers, artists, journalists, academics, vegan folks, and many more. **Signal:** "I'm in this specific community." **Best for:** if your niche has a clear topical instance, joining it gives you a built-in local audience. ### Country / language instances Examples: `mstdn.jp`, `mastodon.uno`, `social.tchncs.de` **Signal:** "I post in this language" or "I'm in this region." **Best for:** if your audience is regional or language-specific. ### Personal instances You run your own server. Your handle is `@you@yourdomain.com`. **Signal:** "I'm serious about Mastodon" or "I care about ownership." **Best for:** advanced users — covered in next lesson. ### How to pick 1. **Match your primary niche** if a strong topical instance exists. 2. **Generalist if not.** `mastodon.social` is fine. 3. **Don't over-think.** You can move later. ## Lesson 3: When to Run Your Own Running your own Mastodon instance is a real option. It's also a real commitment. ### Why people run their own 1. **Branded handle.** `@max@boltastartup.com` reads cleaner than `@maxbolta@mastodon.social`. 2. **Full ownership.** No instance admin can ban you or shut down your home. 3. **Customization.** You can tweak rules, themes, and federation as you like. 4. **Signaling.** Running your own signals "I'm serious about the fediverse." ### What it costs 1. **Money.** $5-20/month for a small server. 2. **Time.** Initial setup is a few hours. Ongoing maintenance is real (security patches, server updates, occasional debugging). 3. **Attention.** You're now a small server admin. Things break. ### Single-user vs multi-user You can run a single-user instance just for yourself. Easier to maintain, less moderation work. You can also open it to others (friends, your team, your community). More work, but higher reach. ### Hosted alternatives If you want a custom domain handle without running your own server, services like `masto.host` will run an instance for you. ~$10/month, no maintenance. ### Should you run your own? Yes if: - You're a developer comfortable with server admin. - You have a custom domain you want to use. - You're in this for the long haul. Probably not if: - You're new to Mastodon. - Server admin sounds like work you don't want to do. - You're not sure how committed you are to the platform. ### Migration is real If you start on a generalist instance and decide to move to your own, Mastodon's account migration tooling handles it. Followers come with you. Your old posts stay on the old account; new posts go to the new account. ### Common myths 1. *"Instance choice is permanent."* It isn't. Migration works. 2. *"Running your own instance is required to be taken seriously."* It isn't. Plenty of well-respected Mastodon users are on shared instances. 3. *"All instances federate with all others."* Most do, but some have defederation policies. If your instance defederates with another, you can't see their posts. ### Action Steps 1. Pick an instance. Apply Lesson 2's framework. Don't take more than 5 minutes. 2. Sign up. Verify. Set up basic profile. 3. Tell yourself: this isn't permanent. You can move later if needed. Move on. Instance choice is a small decision dressed up as a big one. Make it; move on. Next lesson: profile setup and the content warning convention. ## Relevant links - [Bolta University](https://bolta.ai/university) - [Mastodon & the Fediverse](https://bolta.ai/university/courses/mastodon-fediverse) - [Bolta pricing](https://bolta.ai/pricing)
