Do you think it is ethical (or even lawful) to copy the category structure from a major directory (excluding DMOZ) when setting up your own directory? I've seen a beauty but don't want to upset anyone.
Most big directories have copied the directory structure from DMOZ or BOTW in the first place. However I believe it's better to create your own to avoid duplicate content penalties. Of course there isn't much room for originality but what I mean is to change the words, use synonyms, merge categories, split large categories etc. One of the few directories that has a unique structure is gimpsy and the results are obvious.
