Bluesky Strategy for UK Journalists: AT Protocol Guide

What Bluesky and the AT Protocol are

Bluesky is a microblogging platform built on the AT Protocol (Authenticated Transfer Protocol), an open networking standard designed so that a user's identity, social graph, and content are not locked into a single company's servers. This is a meaningfully different architecture from a closed platform like X or Instagram, where the entire social graph exists only within that company's systems.

For UK journalists, the practical benefit is portability: a Bluesky handle can be tied to a domain the journalist or outlet controls, and in principle a user's account and social graph can move between different AT Protocol-based applications without starting from zero, an approach the ATProto documentation describes as protecting users from being trapped inside one company's walled garden.

Adoption among UK journalists grew significantly following changes at X around 2023-2024, with many reporters, columnists, and outlets establishing a Bluesky presence as either a complement to or partial replacement for their X activity.

Moderation vs decentralisation: how Bluesky differs from Mastodon

• 1Bluesky runs a default moderation service and central community guidelines, documented at Bluesky Help.
• 2Unlike a fully decentralised network, most users interact through Bluesky's own app and default moderation layer.
• 3The underlying AT Protocol allows independent, third-party moderation services to be built and adopted by users who want different standards.
• 4This creates a middle ground: more user choice than a single centrally moderated platform, but a stronger baseline than networks with no default moderation at all.
• 5Journalists should understand which moderation layer applies to their account and reporting, particularly for harassment or safety incidents.

Custom feeds for editorial control

• ›Custom feeds are algorithm-driven timelines built by any developer on top of the AT Protocol's open data.
• ›Journalists can build or subscribe to a feed focused on a specific beat — UK politics, a particular investigation, or a regional topic.
• ›This offers substantially more editorial and discovery control than a single platform-wide algorithm.
• ›Newsrooms can build a branded feed aggregating their own reporters' posts as a discovery tool for readers.
• ›Custom feeds can be built and shared without requiring Bluesky's direct involvement, since the protocol is open.

Audience growth strategy

• ⚠Verify the account's handle against the outlet's own domain to build reader trust immediately.
• ⚠Engage in beat-specific custom feeds and communities rather than relying solely on the default algorithmic feed.
• ⚠Cross-promote Bluesky presence from other channels during the platform's growth phase, when discovery tools are still maturing.
• ⚠Track total audience size honestly — Bluesky remains smaller than X's at-scale reach, so set realistic expectations.
• ⚠Monitor Reuters Institute Digital News Report data for shifting UK audience distribution across platforms.

Bluesky onboarding checklist

• Handle verified against the outlet's own domain rather than left as the default bsky.social subdomain.
• Profile bio clearly states outlet affiliation and role for reader trust.
• Relevant custom feeds identified and either subscribed to or built for the outlet's beat.
• Moderation settings and reporting process understood for handling harassment or abuse.
• Cross-posting or syndication tool configured if maintaining multi-platform presence.
• Article links included consistently to support referral traffic measurement.

Tool recommendations

Common mistakes

• ›Leaving the handle on the default bsky.social subdomain instead of verifying against the outlet's own domain.
• ›Expecting X-scale reach immediately, given Bluesky's smaller total audience size.
• ›Ignoring custom feeds entirely and relying only on the default algorithmic timeline.
• ›Misunderstanding the moderation model and assuming full decentralisation with no baseline standards.
• ›Failing to track referral traffic from Bluesky separately, obscuring its actual audience contribution.
• ›Not cross-posting efficiently across Bluesky, Mastodon, and X, missing an easy way to maintain multi-platform presence.
