TheNextWeb author Zee published a case of design plagiarism, which is in his view the biggest rip off ever. The simularities are indeed stunning, virtuelly every aspect has been copied, as Zee shows on his blog.
Until today I considered the design rip off at StudiVZ the biggest. They copied everything from Facebook and put their copied css-Files even in a folder called Fakebook. But since Facebook as well as StudiVZ are rather known for great usability than for great design, the case above is moving forward to be the first in place.
Well, about time DesignProtection.com opens up. Protected designs are definetly less ripped off than unprotected ones.
