“Develop for web using the best technology available
If you’re a web developer, and the choice is yours, choose to embrace the most appropriate technology on future projects. If you have lingering Flash dependency on existing sites that can be transitioned to a Flash-less site without losing too much of the experience, upgrade them to use more modern standards. If you’re doing stuff that just isn’t possible or economically viable without Flash, use Flash. It’s that simple.”
