      @mjackson That’s true, but diffing has its own set of performance trade-offs. It’s not an unvarnished win.

      @floydophone @tomdale @mjackson I think the best thing React has going for it is "Thinking in React"; the programming model not library.

      @wycats @floydophone @tomdale It lets you think about building pages just like you do on the server, with all the data at once.

      @mjackson @floydophone @tomdale The diffing is not free, but it's cheap enough for small/medium size lists.

      @wycats @floydophone @tomdale I'm betting it's good enough for just about any size list. @jlongster has an example http://jlongster.com/Removing-User-Interface-Complexity,-or-Why-React-is-Awesome …

      @fivetanley @wycats @floydophone @tomdale Exactly. Nice thing about virtual DOM is # of DOM nodes stays consistent. Doesn't grow with data.

      @mjackson @fivetanley @floydophone @tomdale perhaps updating N-sized list is always fast enough regardless of complexity.

          @mjackson @floydophone @fivetanley @tomdale don't see why the observable approach can't reuse DOM nodes.

          @wycats @floydophone @fivetanley @tomdale Seems like it would need to be built in to {{#each}}. In any case, the lib should do it not me.

          @mjackson @floydophone @fivetanley @tomdale our current lib impl reuses nodes far too infrequently but not fundamental. Improving.

          @wycats @floydophone @fivetanley @tomdale And I think it should default to reusing as much as possible. Make me work to have it otherwise.

          @floydophone @fivetanley @mjackson @tomdale don't see how inserting a single row in a big list can ever be DOM constrained.

          @wycats 4. Diffing only tracks what is actually rendered. Observables must track entire underlying model... @fivetanley @mjackson @tomdale
