What Bluesky is

Bluesky is a microblogging platform — structurally similar to X in its short-text, reply, and quote-post format — built on the AT Protocol, an open, federated standard developed with significant early backing from Twitter co-founder Jack Dorsey. Unlike centralized platforms, the AT Protocol is designed so that users retain ownership of their identity (via a portable DID) and their follower graph, meaning they can theoretically switch to a different AT Protocol-compatible app without losing their audience.

Why it matters for social media strategists

Bluesky grew substantially through 2024 and into 2025 as users sought alternatives to changes on X, and its active user base as of 2026 includes a disproportionate share of journalists, technologists, academics, and creators. For brands targeting these audiences, or for those wanting to participate in news-adjacent conversations, Bluesky represents a credible supplementary channel. Its algorithmic feeds — which users can customize or swap entirely — differ meaningfully from the opaque recommendation systems on centralized platforms.

A concrete example

A media company publishes analysis threads on both X and Bluesky. Over six months it observes that Bluesky engagement, while lower in raw volume, skews toward replies and reposts from other journalists and researchers — a high-quality audience for their editorial goals. The cross-posting effort costs little marginal time, and the platform-specific customization allows the team to adapt link placement and thread structure to each network's norms.

How to get started and what to measure

Claim your brand handle (Bluesky supports custom domain handles, so yourname.yourdomain.com is a valid Bluesky identity). Post consistently in the format that fits the platform — short text, threads, and reposts of relevant content. Track follower growth, reply quality, and the profile of accounts that interact with you. Because Bluesky's recommendation system is more user-controlled than most, showing up in curated feeds often depends on engagement and reputation within your niche rather than pure recency.
