Japanese “secret” Button on LinkedIn

What it signals here

professional use

Occasionally used by thought leaders to tease 'industry secrets' or exclusive insights in post hooks to drive engagement.

post context

Placed in post openings like 'The ㊙️ to scaling your startup that nobody talks about...' as a clickbait strategy.

appropriateness

Borderline appropriate — acceptable when used sparingly in casual or creative professional posts, but out of place in formal corporate communication.

comment use

Commented to acknowledge a post that revealed something genuinely insightful or counter-intuitive about an industry.
