I'm lost. What is this site about? What is the feed page showing me and what am I supposed to do?

I couldn't find the "about us" page, which normally helps me understand what the site is about, and what I should look for. It may be helpful to include that (and a menu button / menu bar at the bottom..?)

It's probably me, but this is too minimalist and context-free for me to actually get anything out of it. Maybe I'm not part of the target audience?
