Number of contributors per platform
It would be nice to honour the supporters who don't use Patreon, even by just including their number. In the metadata files I'm working on in #44 (closed) it would be easy to include different categories (numbers are fictitious):
financial supporters:
Patreon: 800
Liberapay: 400
Tipeee: 200
Ğ1: 100
bank transfer: 100
mail: 50
