How long should a post be?
Short posts (under 300 characters) are easy to read on a phone. Longer posts work when they teach or tell a story, as long as the first line makes people want to tap see more.
Tips for the first line
Lead with the most interesting part: the result, the question or the surprise. Save the background for later.
