Not very interesting. I mean, does it matter whether someone worked at Microsoft or HP or Oracle or Accenture etc. before they lost interest in a big-corp career? Or is Microsoft a special case? Or is Mashable running out of "Top X" list ideas..
This is what I point to every time someone asks me why Mashable, even though it has more pageviews than anyone else, still doesn't matter in tech news. Sigh.
I'm surprised there's not more. Don't any of Paul Allen's ventures merit the list? And the number order is a bit strange. I would assume Valve would be at or near the top of the revenue rankings
