The case for boring technology in social products

Q1Every new social product I see is built with the latest shiny stack — server components, edge functions, novel databases. But looking at the products that actually scaled — WhatsApp (Erlang), Reddit (Python monolith), Discord (Elixir) — they all chose 'boring' technology that their teams knew deeply. Is there a lesson here?
Q2I think the deeper point is about team velocity. When your stack is boring, every engineer can debug any part of the system. When it's novel, you get knowledge silos and 'only Alice understands the edge function caching layer.' For early-stage social products, iteration speed is everything.

推荐系统的冷启动不是技术问题,是产品问题

Q1我在做社交产品的推荐系统时,冷启动问题困扰了我很久。技术上有很多方案——基于内容的推荐、协同过滤的迁移学习。但我越来越觉得冷启动本质上不是技术问题,而是产品设计问题。
Q2对。我们最近的做法是把冷启动期变成一个'探索游戏'——新用户先进入一个 curated 的高质量内容池,系统通过他们的浏览、停留和互动快速学习。关键是让这个探索过程本身就是有趣的,而非一个需要'熬过去'的阶段。
