TThe essence of good design is that form follows function. Don't let the sparkle of the technology get in the way of what you're trying to do. At the end of the day, it doesn't matter what language the nifty new component is written in, or how the data gets written to the server. What really matters is the design.

DDesign is the heart of your project. If you develop a good design, the project will succeed. If you skip the design and jump right into the details, you'll end up with a real mess. Ask yourselves these sorts of questions first.
