Most of the Logic Tropes index could find a home rewritten as articles or on the wiki, as would about half the Intelligence Tropes. "TV Genius" strikes me as a particularly good candidate, if we don't already cover the idea in some form (which is more than possible).

There's also a large set of tropes that would make good resources for an article, but which would require a very different treatment to flourish here; "And Man Grew Proud" comes to mind.
