Very cool. I think WebGL will be what gets me in to JS and client-side development.
Hope so! :) Feel free to let me know if you have specific questions, and if I can flow them into the podcast I will. I'd rather the episodes actually answered peoples' questions than be based on my hunches as to what's interesting or helpful.
Well, I know it's a premature worry for a beginner, but I'd be interested in the topic of how different (OS, Browser, GraphicsVendor) permutations stack up in terms of performance and compatibility. Are there any particular sweet spots or laggards?
