Rajesh has a screen shot of a dual language AdSense ad unit which displays one ad in Englishh and one in Hindi.
I’ve seen dual language ads before and always thought they were probably a glitch in the system but in the last few days I’ve talked to a number of people who think that it could be more than that.
Whether they are a new feature, a glitch or a test AdSense are doing is anyone’s guess really.
