I really love this podcast and all the discussions but I also think one needs to really deep dive and try to implement the this stuff. I tried to implement the twitter app for episodes 6 - 11 a long time ago (already shared it here) and now I want to continue with "Twitter Poster" (episodes 21 - 27) which I think will be fun. This is a preparation step: https://github.com/jumarko/functional-design-in-clojure/pull/4/files (saving authentication state in an atom instead of returning it explicitly). Any feedback welcome! Hopefully, I'll have a working Twitter Poster in a few weeks.
