TCK (Third Culture Kid). My life experiences range all the way from living in a thatched-roof hut in the jungle, to a high-paying tech career in California.
Mastodon is an ethically-designed, open-source microblogging platform consisting of a network of independent servers that talk to each other (part of the "fediverse"). It can be thought of as an alternative to Twitter, for example. This particular server focuses on two things: First, fighting oppression, exploitation, abuse and victimization, whether of humans, plants, animals, or the planet itself. Second, helping people heal from any of the above that they have experienced or witnessed.
