I created http://benchurch.me/hackersearch a tool to search who's hiring threads using react and found it to be a great starting point for jumping off into the library.

It was simple, had a single external data entry point, was a suitable use case for diving into functional paradigms and has a lot of room for extension in the future as I continue to learn
