Tips for Bluesky Posts

300 characters — more than Twitter, less than Threads. Bluesky sits neatly between Twitter's 280 and Threads' 500. Enough for a complete thought.
Bluesky counts grapheme clusters. This means an emoji counts as 1 character, not 2. More intuitive than some other platforms.
Custom domains as handles. Bluesky lets you verify your identity by using a custom domain as your handle (e.g., @yoursite.com).
Alt text is generous. At 2,000 characters, Bluesky's alt text limit lets you write detailed image descriptions for accessibility.
