13 hubs
Broad coverage
Subjects like Linux, welding, geography, finance, cooking, and home projects each get their own cluster page.
Specific calculators, planners, and explainers for jobs that usually get buried in forums.
Browse the catalog
The site is intentionally broad, so these hubs group related tools into tighter clusters that are easier to browse, easier to crawl, and easier to trust than one giant alphabetical list.
Use topics when you know the subject area but not the exact tool yet. If you are working through a multi-step job, start with workflow pages. If you want to see the strategic clusters the site is trying to deepen, browse the priority collections.
How to use topics

Better discovery
Many tools solve oddly narrow problems, so topic hubs provide a more natural entry point for first-time visitors.
Next step
Once you find one relevant page, topic browsing makes adjacent calculators and explainers visible without another search round-trip.
