Education in the town's taxonomy is broad on purpose: courses and edtech, yes, but also schools, tutorial sites, documentation and reference — anywhere a visitor goes to learn something rather than to buy or use something. Developer documentation that stands on its own domain lands here rather than in dev tools.
These are steady squares. They arrive, they stay, and they collect views at a constant rate for years, which makes newest-first the interesting order on this page: the arrivals are the new courses.
A school or a course with many domains can hold one square each. Every square is a dollar, once, and the deed that proves ownership is a link mailed to the address you claim with — no account to keep alive.
