- professional use
- Extremely rare and generally discouraged in professional posts, but occasionally used in self-deprecating anecdotes about past mistakes or learning moments.
- post context
- May appear in 'lessons I learned the hard way' storytelling posts where the author acknowledges a past blunder with humor.
- appropriateness
- Low appropriateness in formal contexts; slightly more acceptable in casual thought leadership or personal branding posts aimed at younger audiences.
- comment use
- Almost never used in comments; if it appears, it typically signals the commenter is posting casually and breaking professional norms.
