How about the Percent increase in revenue? That, too, is a critical metric. What does your fancy math tell you about that?
That is right. They are finally in growth mode after years and years of searching for a revenue stream, they are finally building it up.
Based on your example, Steve Jobs, Mark Zuckerberg, Bill Gates and Paul Allen, just to name a few, would also have had those same feelings...once. Now they don't.
As dangerous as it is to project success from this early stage of earnings, it is ridiculous to look at their current revenue rate and claim it to be the net sum gain of the past 10 years.
