Re: [keso] Re: feedburner是如何计算订阅用户的？

这里给出了解释，在feedburner的服务论坛找到的：
http://forums.feedburner.com/viewtopic.php?t=2764
这样看来，feedburner的统计数Feed Live Circulation
并不能说明订阅你种子的人有多少，只能知道在24小时内，
查看过你的feed的ip数?iTunes会自动退订不活跃时间超过1星期的feeds。

Our daily stats show how many individuals consumed your feed in a 24 hour period (from midnight to midnight, central standard time). Our live circulation shows feed consumption on a rolling 24 basis - the last 24 hours, up to the moment you're looking at your circulation page. As a result, the numbers will diverge slightly, which is to be expected.

Since RSS has no mechanism to uniquely identify your subscribers, we have no way of counting an aggregate of all subscribers who've subscribed using various applications - all we can do is measure how many of them access your feed in a given time, and then report back to you so you can interpret the info. A good rule of thumb is that your total number of subscribers is probably close to your high-water mark for subscribers in any period (daily or 'live' circulation); it's to be expected that not all of them will access your feed on a given day.

Also note that iTunes, the most popular podcast client, has a 'feature' that will unsubscribe anyone who doesn't listen to your mp3s for a week or more... so people who've indicated they subscribed but who don't listen for a while may very well be unsubscribed by iTunes, which means that we'll stop seeing them as subscribers.

退订的可能性当然存在，
但是同时7人退订，而且，
我遇到的这种波动是经常性的，
反复了很多次了，
所以，我认为不是因为退订，
而是feedburner订阅规则的问题。

为什么没有7人退订的可能？

估计是24小时内独立IP访问数量
