Fair points all around; I agree wholeheartedly. Here's what the problem has been thus far: do we focus on making the framework better, or do we focus on selling it? Personally, I'm much more comfortable with making sure we deliver the goods before we try to sell it. That's what SproutCore 1.5 is about. This is the first smoke signal of where we want to head with the framework, and people can take that for what it is. The core of the framework is amazing and fun to work with, but a lot of our demos are old and ugly. In many cases, our documentation has been or is still lacking and we're working on that too.
This obviously makes it a tougher sell. However, when people actually start building apps, their responses are overwhelmingly positive and they're very happy with their decision. I would much rather this problem than vise versa. We're going to work on the outward facing stuff, I promise.
