Seems it's not allowed to simply return "Nothing found" anymore. I don't want blackbox algorithms serving me stuff it thinks I want.
I like the design. I like the domain. I don't understand grouping of content at all. People want siloed communities. If this is just tags, I'm not interested. Twitter had that and it was a nightmare.
EDIT: also, yeah. Parroting other answers. non.io should take me directly to content. I went there to take a look as I got home and it's... a marketing page, with no information (at least, from a cursory glance) as to how to get to the content.
