And by the way, the ownership table that is linked to isn't even CORRECT. Not even remotely.
Sinofsky isn't listed, and just 2 weeks ago he reported 737,000 shares, which would make him #4 on that list. [1]
Ray Ozzie has just under 1 million shares, and again he's not listed. [2]
The way you assemble these kinds of tables is by mining the SEC filing Form 4, "Statement of Changes in Beneficial Ownership of Securities". But you have to include every Form 4 for your data to be at all accurate.
So already we can see that Elop is #9, and that's just by me guessing two people who seemed conspicuously absent. There could be dozens of others. And don't forget that non-executives don't have to report their shares. I would bet a few grands that there are senior developers who have been working at Microsoft for 15 or 20 years who own more than $3M in stock.
In fact, I just cast my first ever "flag" vote on HN. (With gusto, I might add.) This doesn't deserve the #1 slot.
