Duolingo is one of the most popular language learning tools out there. I used one of their data sets and to explore which of the most common languages are easier or harder to learn on Duolingo, and how that compares to which languages are hardest to learning in a classroom setting.
Reddit has a huge variety of subreddits with different opinions and different topics. I wanted a way to observe/quantify differences between community reactions to the same content. To make this, I compare opinions from two different communities on Marvel's Iron Fist, a netflix show with mixed reviews; one community is Marvel fans, the other a general tv audience.
