Article topics

Blog articles grouped by subject rather than by the tool they happen to mention. Categories split the catalog by what a tool does; topics cut across it, so an encryption explainer and a password-strength piece sit together even though one is filed under security tooling and the other under text analysis.

A topic gets its own page once 3 or more articles cover it. Subjects with less than that stay listed on the articles themselves - collecting a single post behind its own URL would just duplicate the post.
