It's market share/installed base/whatever time! Net Applications' figures had been under review for a while, and now we know why: they've finally done what should have been done ages ago. Namely, they've added country-level weighting to their figures. They also added this retrospectively, meaning all previous figures have been updated to reflect the change. This has devastating effects for some.

I should have read the linked article, it explains what they did well enough to actually make sense ( the meaning of country-level weighing just didn't click right ).
I should make a point to always look deeper when something that should be, relatively, simple seems to be done so wrong...

hrm.. now only if I could remember the correct term for the weighing algorithm... oh well.

Well, they probably have statistics from let's say 10.000 English sites. And statistics from 100 Chinese sites. So if for example, in the English sites 10% of the visitors are using OS X and on the Chinese sites, only 0.1% are using OS X, the final statistics will say that ~10% of the world wide population uses OS X. How accurate is that? If China has, say, 300 million internet users, it is unfair to not give more weight to each of those 100 sites in Chinese than to each of the 10.000 sites in English. I don't say the math is perfect, but it's better than it was before for sure.
