A piece of software that fills the hyper-specific niche, “nncp but easy for anyone to setup and use”, could do a whole lot of good in the near future.
I installed it but have yet to configure or try it myself. It hasn’t seemed worth the (non-trivial) effort when I only know maybe half a dozen people who would be both capable of and interested in using it to share stuff with me. And I’m an anarchist with a goddamn Mastodon account!
