How do they measure these stats?
They aren't reaching into my PC so they're only checking when I [X].
So it isn't it always just measuring "Os percent from user who [X]"
E.g. Steam only check people with Steam. Slash Dot can only going to measure PCs who go to Slashdot. AOL.com is only checking Boomers.
