Mastodon vs ShareLove Letters: the short verdict

At a glance
Decentralized, open-source social network
Mastodon is open-source, decentralised microblogging. Instead of one company running one site, anyone can run a server - an instance - and those servers talk to each other over the ActivityPub protocol, so an account on one can follow, reply to, and boost accounts on any other. Collectively that network is the fediverse. The design decision that follows from this is the one that matters. There is no global algorithmic feed. Timelines are chronological, there is no advertising, and moderation policy is set by whoever runs your instance rather than by a single global trust-and-safety team. That makes moderation local and legible - you can read your server's rules and know who enforces them - and it means the experience varies by server, which is genuinely a trade-off rather than a pure win. Choosing an instance is a real onboarding cost that centralised platforms do not impose, and it remains the single biggest reason people bounce. For a founder or an organisation, the practical appeal is ownership. You can run your own instance on your own domain, verify your identity through a link on your own website, and keep an audience that no acquisition or policy change can take away. Account migration is built in: you can move to a different server and bring your followers with you, which structurally limits how much leverage any one operator holds over its users. The numbers are worth stating plainly rather than optimistically. Mastodon peaked at roughly 2.6 million monthly active users in November 2022, immediately after Twitter's acquisition, and has settled to somewhere between 750,000 and one million monthly actives in 2026, spread across thousands of instances. The wider fediverse has passed 11 million registered accounts with one to two million active. It is a real, durable network, and it is not a mass-market replacement for a large social platform. Governance changed in 2025 and 2026. Founder Eugen Rochko stepped down as CEO after ten years and the project completed a transition to a non-profit structure with more than 3 million euros in funding and a board that includes Twitter co-founder Biz Stone, explicitly to make the platform, in its own phrasing, hard for any single wealthy owner to capture. Funding comes from donations and grants rather than advertising. How it compares: Bluesky is the closest peer and is also protocol-based, but is easier to join and more centralised in practice; Threads is federating slowly and is owned by Meta; X is the incumbent it was built to be an alternative to. Mastodon's distinguishing claims are no ads, no algorithm, and no owner. It suits communities and individuals who want portability and local moderation. It is a poor fit for anyone whose goal is maximum reach.
Write and share beautiful digital love letters
ShareLove Letters is a free tool for writing a real letter and sending it as something worth opening — the recipient sees a sealed envelope with an animated wax seal rather than another block of text in a chat window. It exists for the messages that a text message flattens: an anniversary, an apology, a thank you, a condolence, a letter to your future self. The editor supports formatting, custom fonts and colours, and photo uploads, and there are over thirty templates across eleven occasions for people who know what they want to say but not how to start. A library of more than seven hundred quotes is organised by mood and occasion for the same reason. Privacy is treated as part of the product rather than a settings page. Letters are stored with AES-256 encryption, can be locked with a password, and can be sent anonymously without an account at all. Once a letter is opened, registered senders get a notification, and recipients can reply. Writing and sending are free, with no paid tier — the meaningful difference is how long a letter survives. A guest link expires after seven days; creating a free account extends that to thirty and adds open and reply notifications, which matters if you are sending something you would rather not lose. Beyond the letters themselves the site publishes printable templates, themed collections, quizzes and a writing blog.
