Yet very few people actually made money on it. Certainly not the average joe. 99% of those dot-com mania companies don't exist today. One of the intents of my post is to say that, yes, something can be super-duper awesome, like the internet. But that doesn't mean there will be a lot of money to be made in it.
The dot com bubble was indeed a crazy time. But it is easy to overlook that before it happened, no one knew what the internet was. After it was all over, no one didn't know what it was.
