The concept of a public Unix box is neat, but why? Is this a way to connect with like-minded people? Is this locational? I've known about this for a while and I don't really understand the purpose. What is anonradio? Lipsy gopher show? I have so many questions, I'd love some answers.
Anon radio is SDFs internet radio. https://anonradio.net/ You too could participate in it.
Anyway, the pubnix also allows you to host a simple static website and a gopherhole, for example.
