RDXW 热点雷达是什么?
RDXW 热点雷达是一个中文多来源热点聚合与自媒体选题工具，每 3 小时更新体育、电竞、AI、娱乐、平台热议和 GitHub 项目。它把 24 小时、3 天、7 天窗口分开展示，并结合微博、抖音、B站、虎扑、知乎、百度热搜、IT之家、36氪、GitHub、Product Hunt 等来源作为旁路参考。RDXW 的重点不是复制单个平台热搜，而是帮助创作者先看多源交叉、持续发酵、强选题和可核对来源，再决定是否写成短视频、图文、播客或周报。
RDXW Hotspot Radar is a Chinese trend monitoring page for creators, editors, and growth operators who need fast topic discovery. The site refreshes every three hours and separates sports, esports, AI, entertainment, platform discussion, and GitHub signals into 24-hour, 3-day, and 7-day windows. It combines current ranking pages with source radar cards from Weibo, Douyin, Bilibili, Hupu, Zhihu, Baidu Hot Search, IT Home, 36Kr, GitHub Trending, Product Hunt, Douban, and Tencent Video. RDXW is not a primary news publisher; it is a filtering layer that helps users find multi-source topics, check original sources, identify creator angles, and decide whether a story deserves a short video, article, podcast segment, weekly report, or deeper manual research. Pages with stronger cross-source evidence are kept indexable, while weaker single-source detail pages remain available for browsing but are not pushed to search engines.
