+## Derived Data Experiment ##
+
+This branch is intended to explore some solutions to the question posed here:
+htps://github.com/rackt/redux/issues/291#issuecomment-125047678
+
+Do ActionCreators need to know how to call several API's to update various components?
+
+vladar suggested a couple of approaches:
+
+1. Move the API calls into the reducers
+2. Allow reducers to emit side effects for the API calls.
+
+My general approach is going to be:
+
+1. topAuthor is actually derived data, so it doesn't belong in the client state (except possibly
+   as cached data)
+
+2. if all state is on the client (i.e. no API's), this is obvious --- update the state with the raw data, and the component itself (or something like reselect) is responsible for computing the derived data
+
+3. if the state is stored on the server: Will address in future commit.
