Simon Willison on link blogs:

Link blogging is a pleasantly low-pressure way of writing online. Found something interesting? Post a link to it, with a sentence or two about why it’s worth checking out.

People have commented on links they found on social media for many years. For some reason the big white canvas of a blog editor is intimidating though. Sometimes I wonder if smaller text input boxes would take the pressure off. I think P2 got this right many years ago.
