LinkedIn has rolled out a new feature, pinned comments. This is a good one.
It's good for sharing links as LinkedIn generally doesn't like content with links so this is a good workaround.
It's also good for an additional PS or follow up comment and it feels conversational in style.
In my example below, I shared a funny story about handing in physical essays at university and using the old fashioned printer, and I followed up with a pinned comment showing what it looked like (for those born after 1985)
This post got 65,000 impressions and the comment got 3,100 impressions.
