I have no interest in social media and don't really understand the concept of what a Like Feature is.
Surely if you agree with something a poster has written you note your approval in a written post.
It takes time to think about what you're writing and the views you're expressing.
And presumably if you're on FT you have the time to do that.
That's the joy of FT.It encourages good argument and the occasional polemic.
Leave Likes to the kids.
