From 1point 3acres bbs\nintro - both\nsql - video call\n\nproduct:\nAdd group call - how to analyze based on tables\nWhat questions to ask the recipients about needs for the group call? 这个问题我一开始有点懵，问他是问survey问什么问题嘛，他也肯定了，说了几点我觉得太干巴了，又提到competitor benchmarking，他follow up怎么知道competitor的adoption？\nlimit group call size\nexperimental design metrics\nengineering 说total call的总量作为metric行不行\nback to 实验设计，说到network effect的时候有follow up如果没有resources做cluster-based怎么办
