I haven't had time to dig into this yet but I played the tic-tac-toe demo at the bottom of the page and it seems pretty interesting. The code is easy to understand.
How do you see this being used in a "real" application? Do you see it providing most/all of the reactivity or integrating with an existing framework or library?
That's good the hear!
I intend this to be used to write full applications. I've used to proprietary spiritual predecessor to Aberdeen for pretty large projects.
