Are Bluesky and Mastodon worth your time?

2 networks now occupy the space X used to hold, and both are a fraction of its size. That is the obvious argument against bothering. The less obvious argument for it is that reach per follower on both is currently better than almost anywhere else, and it will not stay that way.

What each one actually is

Bluesky looks and behaves like early Twitter. 300 characters, quote posts as a first-class format, chronological and algorithmic feeds you can choose between, and content labels you apply yourself. It is centralised enough to be simple.

Mastodon is federated, which is the thing that confuses people. There is no single Mastodon. There are thousands of servers that talk to each other, and your account lives on one of them. Around 500 characters depending on which server, four privacy levels per post, content warnings as standard etiquette, and editing after publishing.

The practical difference: on Bluesky you sign up. On Mastodon you choose a neighbourhood first, and the choice matters, because your server’s culture and moderation are what you inherit.

The case for bothering

Reach per follower is unusually good. Both networks have chronological options and far less advertising competition, so a post to 2,000 followers reaches a meaningful share of them. That has not been true on the large networks for years.

The audiences are concentrated. Technology, journalism, open source, science, design, policy. If you sell to any of those, the density is higher than the follower count suggests.

It is cheap to be early. Building two thousand engaged followers now costs a fraction of what the equivalent took on Instagram in 2018, and the accounts that established themselves early keep the advantage.

Almost nobody is scheduling to them. Which means consistency alone is a differentiator.

The case against

The numbers are small. If you need volume this quarter, these are not where you find it.

Analytics are thin and always will be. Bluesky gives follower counts and basic engagement; impressions are derived rather than reported. Mastodon deliberately collects very little, because that is the point of it. If your client judges channels by dashboard numbers, you will struggle to make the case.

Marketing register is punished, hard. Both communities formed partly in reaction to advertising-driven platforms. A corporate voice that passes unnoticed on LinkedIn stands out badly here.

Mastodon has a real learning curve. Servers, federation, content warnings. An hour to understand properly, and the mistakes are visible.

Who should be on them

Yes, clearly: software and developer tools, open source projects, science and research, journalism and publishing, policy and advocacy, privacy-focused products, anyone whose audience left X on principle.

Probably not: local services, most retail, hospitality, anything where the audience is on Instagram and Facebook and has no reason to be anywhere else. A hair salon does not need a Mastodon presence, and saying so is more useful than selling one.

Worth a cheap test: B2B services, consultancies, agencies. Low cost to find out, and the test is 3 months of posting rather than a strategy document.

Getting the etiquette right

Alt text is expected, not optional. Both communities care about it visibly, and people will tell you. This is also simply good practice everywhere.

Content warnings on Mastodon are normal. Politics, food, long threads, anything heavy. Using them well is the difference between welcome and blocked.

Quote posts on Bluesky are conversation, not commentary. Adding your take above someone’s post is the native format; screenshotting instead reads as avoidance.

Post at human times. Mastodon’s chronological timelines mean posting time matters more here than anywhere else in the set. A three in the morning scheduled post is seen by nobody.

A realistic commitment

Do not build a strategy. Build a habit and measure it in 3 months.

Cross-post what already works elsewhere, rewritten for 300 characters rather than truncated. Reply to things in your field, because replies are where both networks actually form relationships. Once a week is enough on each.

Judge it on referral traffic and on conversations started, not on impressions, because impressions are the one number neither network reports honestly.

If after 3 months nothing has come of it, stop. That is a legitimate outcome and it cost you an hour a week.
