Liikuntakartta
What?
A Finnish site that gathers sports and exercise places city by city, in one place instead of scattered over each city's own pages. Billiards is included among the sports.
Why?
It has to be very easy to use, fast, up to date and complete. That is the only reason anyone would use it.
How?
The same technology as Verstaskartta: small data files, a Node script with no packages, and Cloudflare. Joensuu comes first, then other cities.
