Does NextHub provides an endless stream of comments, posts, pictures etc.?
If yes, then it is a Facebook clone.
If no, I like you, but how is the app experience?
NextHub is not like Facebook where anyone can create a posts, it is not about friends or even about people. It mainly revolves on interest centered hubs where publisher can post different type of media including articles. Users can then discuss about the topic in the comment section.
So reddit?
Same thoughts here, how do I see how it actually works without installing it first.
I suggest you put a simple/short video on your landing page.
At the moment that's not possible. It's on our road map to make the hubs and posts visible on the web app without requiring sign up. Hopefully we will have that available soon.
This is interesting, I'll try it out. I hope it gains traction unlike Facebook's Room app from awhile back.
