Bluesky

Short, honest posts with a feed you can actually influence.

Bluesky is an open network with a 300-character limit and custom feeds rather than one algorithmic timeline. Using the right feed-friendly language matters more than timing.

Connect Bluesky

Bluesky doesn't use a sign-in page. You connect with your handle and an app password, a separate password that you can revoke at any time.

  1. In Bluesky, open Settings → App passwords and create one.
  2. In Sosial, open Channels → Bluesky.
  3. Enter your handle (your name alone works, Sosial adds .bsky.social) and paste the app password.
  4. Select Connect Bluesky.

The composer checks these as you type, so a post that's too long for Bluesky is flagged before it's scheduled.

What works on Bluesky

  • Short takes
  • Developer and researcher audiences
  • Linking to long-form work

Tips

Add alt text to every image

It is a strong norm on Bluesky and makes posts accessible. It also shows up in search.

Post smaller and more often

300 characters suits a quick observation. Save the essay for Threads or LinkedIn.

Write for feeds, not a clock

Chronological and custom feeds mean consistency beats timing far more than it does elsewhere.

Avoid

  • Threads longer than three or four posts.
  • Ignoring alt text. It reads as careless to a technical audience.
  • Cross-posting marketing copy verbatim from X.
