Tim Bray has other figures but a recent survey of some of the sites close to Classy shows a consistent Mozilla market share of approx 10% for surfers visiting these sites. That's not too shabby. For classy.dk it is in fact a little bit higher than 10% (approx 14%) but traffic is pretty minimal also. The most interesting one among them is lodret.dk since that has by far the biggest traffic of the surveyed sites. This indicates that Mozilla has made it at least some way outside the pure geek demographic.
