Back in March 2015, I wrote a post where I visualised a large amount of reddit comments, by looking for buzzwords over time and plotting them as a wordcloud. Now that 2015 is over, I decided to plot the remainder of that year.
I made a few small tweaks to the original algorithm. For example, when looking to see how ‘surprising’ a given word is for a given month, the algorithm now looks at the last 12 months to see how prevalent it was (rather than the 12 months of the year, which is less chronological in a way). For aesthetic reasons, I also made sure that each word was only emphasised in one of the months (otherwise ‘Trump’ got ever more buzzword-y over time, and showed up in a lot of the different months).
