检查网站的访问日志,偶然发现居然有Google FeedFetcher的访问日志,顺便计算一下Google的更新频率:

1.发现Google每2小时抓取一次index.xml文件,当然有更新时才会具体刷新内容:

grep FeedFetcher-Google access_log.20060217|awk '{print $4 " " $7 " " $12 }'|grep index.xml
[17/Feb/2006:01:34:16 /blog/index.xml "FeedFetcher-Google;
[17/Feb/2006:03:34:09 /blog/index.xml "FeedFetcher-Google;
[17/Feb/2006:05:34:44 /blog/index.xml "FeedFetcher-Google;
[17/Feb/2006:07:34:05 /blog/index.xml "FeedFetcher-Google;
[17/Feb/2006:09:34:00 /blog/index.xml "FeedFetcher-Google;

2.Google同样每2小时抓取一次index.rdf文件更新

grep FeedFetcher-Google access_log.20060217|awk '{print $4 " " $7 " " $12 }'|grep index.rdf
[17/Feb/2006:00:34:20 /blog/index.rdf "FeedFetcher-Google;
[17/Feb/2006:02:34:25 /blog/index.rdf "FeedFetcher-Google;
[17/Feb/2006:04:34:17 /blog/index.rdf "FeedFetcher-Google;
[17/Feb/2006:06:34:12 /blog/index.rdf "FeedFetcher-Google;

实际上也就是每小时要访问一次.

顺便看了一下Google Reader,也有很多新颖之处,左侧边栏的动感及切换处理感觉很好,相信早晚有一天,Google这个Reader会被越来越多的人所认可和使用.

那么其他的Feed订阅站点呢?
