- Gemini protocol (https://gemini.circumlunar.space/) was proposed as a minimalist, privacy-oriented alternative to both the web and the older Gopher protocol, aligning with the channel’s preference for lightweight, open standards.  
- A startup concept was floated for a Mandarin-learning platform modeled after the Japanese SRS tool Wanikani (https://wanikani.com), aiming to fill the perceived gap in high-quality spaced-repetition resources for Chinese compared with Japanese.  
- Discussion framed the Mandarin-education market as “crowded” at first glance, but the proposer argued it is actually underserved once the focus is narrowed to rigorous, Wanikani-style SRS systems rather than general apps like Duolingo.  
- The conversation briefly touched on the strategic positioning of such a product—occupying the same broad space as Duolingo while offering a fundamentally different pedagogical approach.
