I've been feeling similar to the way you feel for about 9 years, but with Dojo rather than Cappuccino. I stopped worrying or caring about fighting trends I cannot control years ago because it doesn't matter. I focus on building a toolkit that people use to build apps that require solid architecture and APIs. If I spent all of my time listening to or worrying about every critic or every person that doesn't get the power of having something more robust, then I would never make progress and would fail our users. You're not alone in your perspective. And yes, we were indeed all impressed with 280 Slides when it first launched.
