Many very successful internet marketers have one of these 2 opinions:
1. some say: You don't have to invent anything. what working is already out there and people doing it everyday. Just do what's working.
2. The others always say: Never do what everybody else do. Be creative and original. Build a real unique website/service and make a real business out of it, because if everyone doing it, it's already dead.
In short: "Only dead fish swim with the stream"
What is your opinion?
