Nothing extraordinary, same as any other year: donated to orgs supporting trans folk, homeless people, and food banks. Continued to support small business and further divested from fossil fuels, weapons & mining. Advocated for public transport in my local area.
Reply or quote with something good you did for your friends or community this year! 😊👇
I've been saying this to @distributeaid.org's major donors in our end of year emails, but we all really aught to be highlighting the good that we do.
It's not a brag, it's an example to others and normalizes helping your community. 😊

Alright, first wrap up of the year.
It's been a stellar year at @piccalil.li. We've published *so much* and introduced so many great things.
I wanted to reflect on that and let you know what's coming up in 2026.
A massive thank you to everyone who has supported us this year 💛
