I suppose it's hard to tell. http://www.khronos.org/webgl/wiki/Main_Page indicates that IE doesn't have WebGL, for example. According to the google analytics, about 12.5% of our visits to sagenb.org over the last 6 months have been with IE, and about 2-3% or so have used an older version of Firefox that doesn't support WebGL.
So, in particular, it seems that the majority of sagenb.org visits do in fact come from browsers that support webgl. Whether or not their computers support webgl is something that I suppose is harder to tell.
Surely there an easy 1-line test that can determine if a computer itself supports webgl. It would make sense to add to that to the sagenb.org headers to log that information to google analytics. Then we can get a much better idea about how widely-supported it is for our users.
