The Bluesky post limit
A Bluesky post can be up to 300 characters. Bluesky counts graphemes, what you see as one character, so an emoji made of several code points still counts as one.
How to write a Bluesky post
Bluesky shows link previews as cards, so a post can stay short and let the card carry the title and image. Starter packs and custom feeds are how many people discover accounts there.
