Great replacement for the like function in Google Reader.

I think Matt is telling the wrong "code"...

To enable the Ninja mode press these key sequence:

"Arrow up" "Arrow up" "Arrow down" "Arrow down" "Arrow left" "Arrow right" "Arrow left" "Arrow right" "b" "a"

Showing content based on the IP address is dangerous. Since most (or all) Google IP addresses are US located, you will hide your non us-english content.

As Matt says it doesn't have to be cloaking, in fact it is.
It's much better to create all the different language pages and redirect the visitor to the right language based on the IP address he is using.

So how does it work? Which type of complains are processed first?
They have an option to report unauthorized content duplication, I reported some site which has copied a big part of my website and until now there was no response.
