问HN：2025年让你失望的是什么？
问题在于，失望的用户往往不愿意留下反馈，因此问题可能会持续存在。<p>我在这里询问过这个问题：<p>https://www.perplexity.ai/search/why-don't-disappointed-users-l-SWvPF5iASLeWt1FbwB0_Fw<p>那么，今年让你失望的是什么呢？<p>Perplexity.ai没有一个更短的域名让我感到失望，但它告诉我可以使用pplx.ai。<p>显然，失望的性质各不相同，因此这个讨论串实际上可以仅仅是“对任何人/每个人的免费、非请求的负面反馈。”

The issue is that disappointed users are prone to not leave feedback and hence problems may perpetuate.<p>I asked about it here:<p>https://www.perplexity.ai/search/why-don-t-disappointed-users-l-SWvPF5iASLeWt1FbwB0_Fw<p>So what disappointed you this year?<p>Perplexity.ai not having a shorter domain disappointed me, yet it just told me I can use pplx.ai.<p>Obviously disappointment varies in nature so really this thread could be just about "Free, unsolicited, negative feedback for anyone/everyone."
