DanC goes into fairly significant detail on why Flash may actually be the best platform to use to develop games, and then describes how one would go about making a living by doing so. And the best part about it? This post is only the beginning; at least 3 more posts in this vein are expected. DanC is serious about this, and you should be too.
It’s quite a long read, but, as is the norm for Lost Garden, easy to follow. Head over and give it a look.
