In case you have seen http://www.cnprog.com is a straight up rip-off in terms of style on and functionality of Stack Overflow but in Chinese. This may or may not be right/legal cause I am not sure what the creative commons license on this site covers.

As programmers do you ever copy someone design and functionality like this?

Has someone ever copied your design and functionality like this? What did you do about it?

Is anyone else excited that they are going to release the source code for their site (which is powered by Django and jQuery)?

To obtain CNProg's source code (requires subversion):

svn checkout http://cnprog.googlecode.com/svn/trunk/ cnprog
