“instead of using terms like Indie hacker just use software entrepreneur when writing for people outside of the software entrepreneurship business I just don't use abbreviations like mrr without explaining them and Define them first”

Drop the jargon to widen your reach

Jargon signals in-group status but actively repels the newcomers who would have grown your audience. Swap insider terms ("indie hacker" → "software entrepreneur") and define every acronym on first use. As you outgrow your initial niche, clarity is what lets people from different backgrounds and languages cross the bridge into your content.
