Why are you using sproutcore for a static plain ol html page? There is no need to use much js on such a page, is there? And then you are ending up breaking the page on old browsers. Whats the point? Are you using the right tools for the right job?
First, I wanted to test drive SproutCore 2.0. It's always good for framework developers to be app developers themselves; and just from the feedback and collaboration today I've fixed several bugs in SproutCore. So, that's a net positive, even though I'm sorry there was temporary frustration while we got to it, and it didn't help that I was in a plane for part of the day.
The second reason is that this is just the start. I plan to add many more browsing and filtering capabilities over the next few weeks and months. I hope this can be a good demo for how to build data-driven applications in SproutCore.
Thanks for the page though, it is very clear and tells me how much I have been missing on whats been happening in the 'js scene'
