If you like chess, it seems you can play chess with someone on Mastodon (nice activity pub example) https://castling.club/
Banana pancakes, running, C99, 3D/XR, 6502 assembly, Te Araroa... these are just a few of my favourite things.
An NZ hosted Mastodon instance. For all Kiwis and aspiring New Zealanders! Monthly image by @simplicitarian
