Graded!

This is an awesome and fun app. I found myself losing at least two hours reading articles while I was reading this. Bravo! I think your app would have benefited a lot from some of the more advanced react tools, like a flux implementation and react-router, but I recognize that that would have been difficult to learn in the time allotted. My main wish is that the code had been more well commented, you did a lot of cool things, but deciphering them took a substantial amount of time. Besides that I left a few nitpicks and gripes inline.

Tiny code cleanliness suggestion: you've got a bit of whitespace inconsistency in that some of your lines end with whitespace and some don't. I think it's good practice to make sure there's no extra whitespace at the end of each line of code -- Sublime can help you with this (http://nategood.com/sublime-text-strip-whitespace-save). The reasoning behind my opinion: if you're working in a development workflow where you code review other people's diffs and you don't all agree about whitespace, the diffs will probably include some just-whitespace changes. Not the end of the world, but I think it's easier to review when I know all of the changes in the diff are significant (i.e. actual code changes) -- that way I don't need to filter for "that's just a whitespace change" vs "oh, that change is actually part of the new feature or the bug fix". Similar thing applies to newlines at the end of files -- it's convention to make sure there is one because if there's not a newline at the end of a file and you add more lines at the end, the previously-last line will look like it changed because it now contains a newline. Again, Sublime can help you with this (https://forum.sublimetext.com/t/make-saving-newline-at-eof-the-installation-default/9842) Another common thing is to convert tabs to spaces which render more consistently across development environments, this can be found in sublime settings too. This is such a nitpicky detail, and I'm sure you'll find different development workflows which have different rules about newlines/trailing spaces -- mentioning my preferences just so you're aware that people have opinions about these things. :)
