I don't get neither how thousands separator is useful, nor what a "genius" came up with an idea to make comma a decimal separator in computers. I have nothing against either of these things in handwriting (though I personally never separate thousands), but in computing?..
I agree though that this can (and should) be solved at font-rendering level, not at an application level.
