Browser market share is important to a webmaster, or at least it will be until IE6, 7 and 8 disappear (my guess is the year 2532, more or less).
What is the most trustable, versatile and ultimately useful source of browser market share data? Bonus points if:
- It's updated more than once a year
- Data is segmented geographically
- Data is segmented by site category / area of interest
- Data is segmented in other ways (age? that'd be awesome!)
I don't think that the site with the “most” data is necessary the best - but feel free to prove me wrong!
