What am I missing?

This paragraph, perhaps?

The list of open problems on this page is very preliminary. I'm sure there are many problems I've forgotten, and many problems I'm unaware of. Probably all of the problems are stated poorly: this is only a "first step" document. Certainly, all listed problems are described at a very "high" level, far away (so far) from mathematical precision, and can themselves be broken down into several and often dozens of subproblems.

The deja vu may be from this.
