Hey HN, this project was done as part of a course we had this semester. I wrote up a quick blog post for it, and posted the final report for those interested in the details. Note that it can take a while to scrape the data from Reddit using their API, and I'm not sure how happy the server will be if this gets somewhat popular, so apologies if the performance is slow.
