What to do when competitor copies your app (exact design)
pg: Hmm, big chunks of verbatim text.  We regularly have this sort of thing happen to us:    http://www.google.com/search?q="someone+who+is+not+one+of+your+founders"

It's annoying to be plagiarized, but possibly no more than annoying. I.e. the more slavishly someone copies you, the less dangerous they probably are.(In our case, copying chunks of our site is so common that searching for them is a handy technique for keeping track of the ever-increasing list of YC clones.  That search turned up two new ones I didn't even know about.This one    http://www.google.com/search?q="intellectual+property+agreements+that+overlap"

turned up two more.)
