Topics
Topic hubs group apps by the job you are trying to finish, not just by the internal category they happen to live in.
- Good when your task spans more than one category.
- Helps you compare nearby tools that solve the same kind of problem.
- Adds stronger static paths into the library for both users and search engines.
