I can't remember when I noticed this, but I have a 1-year mistake in my stats here at blogspot. When I look at my overall stats (stats, overview, change view of the chart to "all time") and hover my mouse over the individual data points on the chart, all the months are correct back to February 2009. But back further, they're off by a year. So it goes from February 2009 to January 2008, December 2007, and so forth, ending in July 2007, when the stats think I started the blog.
Anybody else have this issue?
