List all blog posts maybe, and list omissions.
Could give the complete list of CTs, together with links to the relevant blog posts.
For each theory, it would be nice with links to nLab, links to basic introductions unless these are listed in one of the blog posts, a note on what MathSciNet has, perhaps a link to a pdf of a MathSciNet search. One could also add more, such as the headings in the DB entries, key authors, etc.
