This is neat, but I think these days if you're going to use a grid it might as well be responsive. For example this is a good responsive grid generator: http://gridpak.com/
Or you could always use Bootstrap.
First thought: dragging doesn't resize boxes. broken.
Second thought: dragging doesn't move boxes. broken.

Other than that, very neat project. Hope you continue to build and develop this further.
Kinda neat, I don't see yet any added benefit over Bootstrap however - the problem it solves in a visual way is not really a problem for a mildly experience web developer and for the beginners it's not enough functionality IMO. As a thought experiment it's cool, as a viable product it would need some work.
I'd reconsider using blueprint, AFAIK it's no longer maintained. I'd go for bootstrap or foundation.
