Thank you! I'm actively working on improving it. Any feedback or feature requests are welcome.

It's funny you mentioned that. I built RNKFlow.com to bring back the old school feeling of Digg to HN and honestly, seeing how clean the interface is for AIBriefs made me think this layout is just more pleasing to the eye.

Glad you liked it. I checked out RNKFlow, and looks neat! I think UI preferences is a tricky topic, a lot depends on the type of reader and how deeply they care about the topics. I started optimizing for my own preferences, but then tweak based on feedback and added views to support other type of readers.
