Hi there -- thanks for your work on Om, it's helped to bend my mind and think about different ways of building apps. I agree completely that the easy snapshot ability is very cool and it wasn't my intention to minimize it. The main reason I dug into this so deep is because after reading your article I had a nagging feeling that using anything other than React or immutable data structures was an architectural dead end. But I'm not so worried about that now; I think that any framework that aggressively batches DOM updates will probably be ok performance-wise, and I think that mutable data structures can perform well. Also I think that some features are easier to provide with mutable structures, such as automatic two-way data binding a la Angular. How do you propagate DOM changes to your models? Manual event handlers or do you have something more automatic? I definitely think that immutable data structures are worth consideration for their snapshotting ability though.
