Why you shouldn't copy us or anyone else

Bob Martens replayed to post "Why Your Startup Shouldn't Copy 37signals" by "the article is referring to ideas and business models, but I think interface design is an example more people can relate to. Have you seen an interface that was obviously copied from someone else’s interface? The copy usually lacks depth and detail. They miss the spacing, the proportions, the relationship between colors and objects and buttons and links. It’s usually pretty close, but there’s something not right about it."
