Idea Lists

This genre of page remains one of perrenial fascinations. The ideas may not always be of the best quality, but they tell you more than you’d expect about the writer’s quality of thinking, and what their circle of competence looks like.

If you don’t have your own Ideas page, I suggest trying to make one. It’s fun.
