I love this myself, but..
> have great debug information
How do you debug WebGL stuff? I find that to be one of the least debuggable things I've ever done with computers. If there's multiple shaders feeding into one another, the best I can usually come up with is drawing the intermediate results to screen and debugging visually. Haven't been paying too much attention to the space the past 2-3 years though, so I'm wondering if some new tools emerged that make this easier.
