Has anyone used Sproutcore for a web application? If so, can you give me a description of your experience? I am currently considering it, but I have a few concerns. First, the documentation is bad/incomplete, and I'm afraid that I'll spend lots of time figuring things out or digging through source code. Also, I'm a bit hesitant to use a project that is relatively new and could undergo significant changes.
Any thoughts from people who have developed in Sproutcore are appreciated!
EDIT/PS: Yes, I've seen this post: http://stackoverflow.com/questions/370598/sproutcore-and-cappuccino . However I'm interested in a bit lengthier description of Sproutcore itself from someone who's used it for a significant project.
