A couple of years ago there was a short thread [webmasterworld.com...] which referenced Matt Cutts and some senior webmasters, on deploying duplicate content across multiple TLD's. To me it seemed straight forward as being OK. Google seemed to work quite well, based on observation. All seemed OK.
But now I'm in two minds. With Panda focused on UI and content, would you still strongly support duplicate content across multiple TLD's for regional ranking? Or would you reconsider your strategy in this area to totally localising the content on each ccTLD?
