The danger of ‘listening’ on social media is that the clues that you’re listening aren’t there! The other person can’t see your interested face. So they don’t actually know you’re listening unless you make it clear to them.
Which means you have to find ways to show your listening. So respond!! Reply to people’s updates so they know you’re there!
One of the golden rules of networking is to spend 80% of the time listening and 20% talking. So stick to this on social media too. Spend 20% of your activity posting your own updates and 80% of the time responding to others.
