There is no doubt that a lot of Googlers are data junkies. I'm that way myself in my Adsense account. I constantly looking at reports for eCPM trends, page views, overall earnings - often by day of the week.

Back in March of this year, there was a bug in the Adsense reporting that ran for two days. I reported this back then in this thread [webmasterworld.com]. It's interesting to note that martinibuster reported a problem on those same two days [webmasterworld.com] one year earlier.

In martinibuster's case the stats eventually started working again. In the case I reported Google never fixed the incorrect data. Just an observation that should be corrected... :) And what's so special about March 25th and 26th?
