It's not just the technical interest community on the lemmy instance, SDF as an entity has gravitas that I appreciate.
It's backed by a 30 year old 501(c)(7) nonprofit established from an even older entity, instead of "someone who spun a VM the other week."
They've handled the abuse of hosting public-facing UNIX systems for decades, so this isn't a crew who will freak out when they get a look at the Internet's gaping hate hole.
This is a community with roots in the BBS era, and the Usenet era, and which maintain their connection to the culture of the ARPANET era via the historical systems (Ya'll played with the TOPS-20 box?). These are people who know that, as platforms go, 'All of this has happened before, and it will all happen again.' and that's the perspective I deeply desire in my platforms these days.
