Gnu social
GNU Social is like Diaspora, Friendica, and Pump.IO [1]. GNU Social is a federated social network that you can install on your own server. There are many instances of GNU Social software. The local one, run by Joshua Judson Rosen is https://NHCrossing.com.
Choosing Freedom
Some interesting discussion on GNU Social, a FLOSS alternative to Twitter The short takeaway from that discussion, and in general, is that if you join or host a freedom respecting federated platform (e.g. NHCrossing.com - an instance of GNU Social), then you both control your content; and can syndicate your content to other centralized services like Twitter. The benefits are many, but it can be summarized as: you gain freedom while also not suffering from lack of visibility or participation in those centralized corporate services.
