Over the next few days, I'll be blogging a bit about how we're running the project, what's new and exciting about it, and what are some of the motivations for coming up with this. We'll also go over some of the basic functionality, and what some of the plumbing looks like.
In the mean time, you can go over to the http://datajs.codeplex.com/, download the library (or the source code!), and play around with it. Feel free to leave feedback, start discussions, file issues, or simply leave a comment here.
