Hole on LinkedIn

What it signals here

professional use

Extremely rare and unusual. Might appear in creative industry posts about 'filling gaps in the market'.

post context

Could be used metaphorically in thought-leadership content about 'the hole in your strategy' or missing opportunities.

appropriateness

Generally inappropriate for professional use unless used very deliberately as a creative metaphor.

comment use

Almost never used in comments — would appear extremely out of place and potentially confusing.
