The mathematical material

• A major problem: how to tie a person's work to him (or her)? In other words, I look up Dirichlet, I see a link to all kinds of things with his name attached. But in most of these, Dirichlet himself is lost in a vast sea of material.
• How to give casual readers some idea of what a person's work is?
• How to make the articles more readable, more interesting, without sacrificing accuracy?
• Use more and cleverer pictures in explanations. Pictures often convey ideas quickly. Explanations of mathematics to the world at large can probably be done only by pictures. But this is a lost art for most mathematicians.
• More (better) survey articles, summarizing quickly the flow of ideas. Better coordination of articles on mathematicians who worked together.
