If there's 400M Win7 customers, and 16K people on this web site posting with Win7 woes, then according to Alexa (which tells us that 0.06% of internet users visit here), that means that 1 in every 15 Win7 customers has a problem sufficiently serious that they need to come here and seek help about it.
Damning methinks...
Your math is a bit lopsided. For the sake of argument, let's say that this forum
is an indicator of the state of Windows 7. Do you account for:
1. Regular members here whose posts number in the tens of thousands?
2. A consistent influx of new 'resident' members, whose posting stats are steadily increasing?
3. That such members post multiple times to a given thread?
4. That many come here with elementary, customization, operational, 'can I do this' and a myriad of other minor issues, unrelated to the state of the OS?
5. And of course, the occasional troll, who knows which buttons to push and enjoys the reactions. These are generally new accounts, quickly abandoned (you might add that to your stats as well...).
I suspect that you belong to the latter. Not a problem here, as it
does have entertainment value, but you should resist the urge to cite numbers that expose your intent.
