I've noticed my feed count as reported on my home page vary by as much as 15% over a single 24 hour period. For instance, just this past Monday I caught the number in the 70s, only to jump up to 98 yesterday.
I researched a bit (See the first two results google returns -- as of today -- for "feedburner fluctuations" here and here) and discovered that not all RSS readers are created equal. According to both, web-based readers seem to report consistently -- which makes sense, since I imagine that Google Reader, Bloglines, and the like all fetch based on cron tasks (er, that's a scheduled task on a unix-based server that launches automatically on specific, pre-defined intervals) . Thick client readers, however, i.e., an application installed on a personal computer somewhere (regardless of operating system), don't fetch unless they're launched or otherwise instructed to pull down fresh content.
There seems to be more to it in my case, however. Looking at my stats over time, my guess is that I'm simply doing some real moving and shaking:
FeedBurner Stats from Sunday, May 6, 2007
FeedBurner Stats from Monday, May 7, 2007
FeedBurner Stats from Tuesday, May 8, 2007
I'm all for jumping up to 98 from the ~50 range just a couple of weeks ago (thanks largely to a recent promo over at BobMeetsWorld), but why would 18 users of Google Reader remove me Sunday? And then re-add me Monday? Or have I just picked up 20 altogether new subscribers? Who all just happen to use google reader? :-0
Please help me understand by posting a comment. Did you just start reading my ramblings this week?
