Is something wrong with AdSense today? I'm getting a horrible CTR (less than 0.5% when I typically get 2-3%) and earnings per click are miniscule. Also, the interface of AdSense has a new quirk in it: the CTR is now shown to two decimal places. If my memory serves me right, that's new - it's usually only to one decimal place; e.g. today it's something like 0.15% instead of 0.2%. So has an update happened today? I can't find word on any of the usual blogs... Thanks.
I also noticed the 2 decimal place thing but my CTR and earnings are right where they should be. Maybe your just having one of those days. Kyle
