判断平台是否完成了可持续转型，可以通过一组剪刀差指标观察：一端是单位交易变现率的变化，另一端是供给侧的满意度指标，例如留存率或净推荐值。如果变现率持续上升，而供给侧满意度同步下滑，这种赚钱方式本质上仍是竭泽而渔。只有当两者同时改善，平台的转型才具备长期稳定性。
在处理对应垂直领域的任务上，和非专家的单纯对话形式相比，专家能交付更专业、质量更高的结果。为了验证这一点，我们直接从它目前已经 1.6w+公开的 Expert 库（大部分是用户创作）里，挑了几个热门的场景进行实测。

A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.。服务器推荐对此有专业解读
