Same, Headline got a click, I was interested. But the UI lacks and your needs to have a feature set. What sort of Social media app? How do I use it? Who is it for? Just some thoughts...
Is there anything specific about the UI that you didn't like?
To answer your questions, we could be called a 'micro-blogging app' as Afari supports posting short text statuses, links and photos. You use it in a manner similar to twitter or facebook.
Regarding the who the app is for, "We built Afari to give people who value privacy, data ownership and censorship resistance, an alternative to centralized social media like Twitter and Facebook. In future, we plan to integrate a token network to help content creators of all audience sizes monetize their content more easily."
Thanks for your feedback. The app login page definitely doesn't do a good job at explaining the app to people in its current state.
