Hi @gaearon - the following statement caught me off guard while reading the docs:

Then, we wrap the components we want to connect to Redux with connect() function from react-redux. Try to only do this for a top-level component, or route handlers. While technically you can connect() any component in your app to Redux store, avoid doing this too deeply because it will make the data flow harder to trace.

Deep prop chains was one of the issues with React that led me to use Flux; the tradeoff for making it easier to trace the data flow is that you need to setup/maintain/trace the prop flow, and more importantly, parents need to know about the data requirements of their children. From my experience, I'm not convinced that this approach is better, but I'm curious to hear what you think 😄
