The first and most important thing that comes to mind regarding this thread - I understand you made it "to look for thoughts and opinions.", but I'm guessing you wouldn't have made it if you yourself weren't uncertain of how to earn a good amount of money on the net.
And I don't care about Google being big and having power - where were they 8 years ago, when Microsoft and Yahoo were already giants, where was Plentyoffish a few years ago, where was Myspace or even a million dollars homepage ?!
It's never really "only the big get bigger", but "smart, cunning and/or hardworking" get bigger and the rest are left behind.
Or, as the saying goes, [SIZE=-1]there are 3 types of people in the world:
Those who make things happen, those who watch things happen and those who wonder what happened.[/SIZE]
