An interesting reality check when it comes to game development in the browser. Personally I’m quite reserved when it comes to implementing bleeding edge browser features. At this point in time, all of the components involved in game development fall under that umbrella.
That’s not to say I don’t fully stand behind the fact that HTML5 will do great things for games, it’s just too early to put all of your eggs in that basket. I still feel it’s completely important to continue researching (and contributing) where you can in preparation for the gradual shift, but there’s still a ton of work to be done.
