I'm a fan of both platforms, and I think they both have a place in the ecosystem. Saidit seems to draw from a more diverse range of backgrounds, while Ruqqus is perhaps more right-leaning (at least, in my experience). Also, if one site goes down, where else will you go, but the other? I mean you got Gab, but honestly it feels so beta. There are a few alternative Twitter clones too, like Minds, and Flote, as well as a few forums of note and Facebook alternatives, but honestly, they don't seem to have much of a community in comparison.

Sites like Voat, Poal, and heck even TheDonald are run by extreme control freaks, why settle there, when you enjoy such freedom here?
