#introductions One thing I have realized is that the term "Little Brother" may be confusing some people at times. I am actually about 6 ft. (2 m) tall; I weigh 250 lbs. (over 100 kilograms); and I'm in my late 30's. So "Little Brother" was always meant to be a bit facetious, or tongue in cheek. But it was also meant as a term of respect for my tribal friends (and others).
Hope that clarifies things!
Mastodon is an ethically-designed, open-source microblogging platform consisting of a network of independent servers that talk to each other (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.
