> Adwords was not critical to Googles share when it came to searches
Even that is arguable, but that is not the topic under discussion. The topic under discussion is this statement you made:
"There are really only TWO decisions that google made that made them successful"
> Adwords allowed Google make money
What in the world do you think "success" means? Despite the fact that this forum is called Hacker News, it isn't really about hacking per se. It's about starting companies. "Success" in such endeavors is not measured by how many people use your product, it is measured by whether or not you make money. To be sure, all else being equal it is easier to make money with a large market share than a small one. But you can make money without a large market share (e.g. the Apple Macintosh), and you can have a large market share without making any money (e.g. the Apache web server).
So maybe you meant to say, "There are really only two decisions that Google made that allowed them to achieve a large market share" or something like that (though even that is arguable). But "large market share" and "success" are not the same thing.
But in September of 2000 Google had neither success nor a large market share. All they had then was a kick-ass product and a really good team. Again, all else being equal, having a kick-ass product is helpful. But it is neither necessary (c.f. Microsoft) nor sufficient (c.f. Napster) for success.
