My view and understanding of behavior trees has been fundamentally shaped by  Alex Champandard’s tutorials and online masterclasses on AiGameDev.com. Alex behavior tree definition is very elaborate and detailed. Other great online resources about behavior trees in games are Damian Isla’s Gamasutra article about the AI in Halo 2, Max Dyckhoff’s presentation about Decision Making and Knowledge Representation in Halo 3, and Ricard Pillosu’s Coordinating Agents with Behavior Trees slides about their use in Crysis.  Joost van Dongen blogs about the role behavior trees play in Swords and Soldiers here and here.

However, there is one HTML5 downside I should mention: browser support for audio is not quite there yet (Flash still does this better). Chrome and Firefox have new Audio APIs that look very promising, but they're neither an official nor de facto standard yet (they even differ from each other!). You might be able to coerce the HTML5 Audio tag (which is supported across browsers) to work for you, but this has its limits (and currently a few browser inconsistencies in "the details").
