推荐答案

简单的部分是谷歌告诉它谷歌阅读器的数量，其他阅读器/聚合器也是如此.

The easy part is Google tell it the number of Google Readers, and so do the other Reader/Aggregators.

对于轮询 RSS/Atom 提要的个人用户，请求中涉及 http 标头，因此通过 IP 地址跟踪用户，当在代理后面时，许多代理在标头中包含原始 IP，这有助于在代理之间进行排序来源.

For individual users polling the RSS/Atom feed, there are http headers involved in the request, so users are tracked by IP address, and when behind proxies, a number of proxies include original IP in header, this helps sort between proxied sources.
