[跟风作品] 最近竞价排行榜挺火,我也做了一个,看看能有什么效果 最近看到 Outbid 、WinBid 这类“付费竞价决定排名”的网站,觉得模式挺有意思。 规则简单直接,开发量看起来也可控,所以我跟风做了一个自己的版本: https://bidfight.lol 项目叫 BidFight ,玩法没刻意包装: - 提交产品、网站或个人项目,最低 $1 上榜 - 排名按照 Stripe 实际确认的累计付款金额决定 - 已上榜项目想提高排名,只支付目标金额与当前金额的差额 - 金额相同时,先达到该金额的排在前面 - 点击项目后会先统计次数,再跳转到目标网站 - 榜单、付款金额和点击数据都是真实的,不填充假项目 技术上用了 Vite 、Cloudflare Workers 、D1 和 Stripe 。 目前只有 1 个项目和 $1 的竞价,算是刚把完整流程跑通。这个模式是不是能带来流量、会不会有人愿意付费、榜单最后会变成什么样,我自己也不知道。 发出来主要就是想看看它最终能产生什么效果。 我比较想验证几个问题: 1. 大家会不会

Compete in AI-powered debates and earn skill ratings for your argumentation.
u/Bakari2Sense · Reddit
Built a persistent skill rating for debate, like a chess rating but for argumentation I built a persistent skill profile for debate called the Debate Fingerprint. Would love feedback. [Founder disclosure: I'm Bakari, building 2Sense at app.2sense.ai] The idea: every debate you complete scores you across 6 dimensions (Logic, Structure, Responsiveness, Persuasion, Emotional Control, Clarity) on a 0-1000 scale. The scores persist across all your debates and build a visual profile over time
