Hello, Mastodon! 👋 We're a small research lab. We build proofs of concept (PoCs) to find out whether an idea really works, and we love exploring curious, exciting things. We're really glad to be here, and we'd love to meet people and build connections around the world. — nDot.io #introduction #PoC #prototyping #research

Growing up, I never saw anyone like me. Let alone climbing rocks, crawling under glaciers, & embarking on crazy expeditions Despite my fear of being perceived, I’ve tried to show my face more to prove that the #outdoors is for everyone like me - #Asians, #immigrants, #POC #AANHPIHeritageMonth

Reminder: You don't get to claim the title of "ally". It's something bestowed (or not) by the people you are *trying to* ally with. Ally is a verb, not a noun. It's something you *do*, and have to keep repeating, for it to count. And only the people you're trying to help get to decide whether you succeeded. #ally #progressive #lgbtq #lgbtqia #disabled #disability #advocacy #neurodivergent #PoC #minority #feminism
