The article makes a point to say that he started with a job that paid a "humble" $60,000 per year in 1997. Based on my quick and dirty run on wolfram alpha, that is the equivalent to $120,000 per year today. Not so much of a humble beginning for a second job out of college.
That is the same salary I was being paid as my second job out of college at WebLogic in San Francisco in Dec 1996. It was a step down from the consulting company I had come from in Chicago but so much better!
