And to follow up on this, I turned up a few more actual projects on Github while searching for uses of the "createSelector" function from the Reselect library.

I can't say anything for how good these projects are, but they ARE actual uses of Redux that are more than a TodoMVC. Here's some links:

https://github.com/jfurrow/flood

https://github.com/FH-Potsdam/shifted-maps

https://github.com/quirinpa/2post

https://github.com/karlguillotte/Ctfs

https://github.com/madou/gw2armory.com

In fact, that GW2Armory app is the biggest one I've seen so far, including some VERY complex reducers and selectors.
