Head Shaking Vertically on LinkedIn

What it signals here

professional use

Extremely rare and slightly risky — if used, it signals casual agreement in comment threads but may undermine professional tone.

post context

Could appear at the end of a reflective post to invite agreement from the audience in a light, approachable way.

appropriateness

Borderline appropriate — acceptable in startup culture or casual thought-leadership posts but out of place in formal corporate content.

comment use

Occasionally used by younger professionals to affirm a colleague's insight without writing a full comment.
