You mean clones of existing business models? If this path wasn't profitable, Burger King/McDonalds/Jack-in-the-Box couldn't co-exist. I've been really confused by this pervasive idea that seems to be going around that the only way to make money, is to think of something no one has thought of before. If that was true, Google/Starbucks/KrispyKreme/Facebook wouldn't exist. People that create new markets tend to make far less, than people that expand/perfect existing ones.
