Flash is transitioning from a platform for websites to a platform for high-performance code, such as gaming, graphical simulations, etc... Whatever strides WebGL might be making at the moment it's a long way from the kind of things Flash 11 is capable of. If Adobe can keep the barrier to entry lower on Flash than WebGL then they ought to have a viable product.<p>Unfortunately for many Flash developers the bread-and-butter site stuff is going away; if you're not skilled enough to transition into gaming and other such computationally intensive work then best to familiarise yourself with the HTML5 suite, and quickly.
