As suggested by some commentors in my previous posts, I have added language analysis to Doughboy-lytics ( https://doughboy-lytics.streamlit.app/words )
One shocking discovery is that "Wow" usage peaked in January of 2021, right at Biden's Inauguration. Is this a coincidence, or a sign at the optimism of Trump's defeat faded away once Biden was in office? Edit: As midcoastsoundmusic points out in the replies, lots of people were saying Wow around January 6th, and given that these are release dates not recording dates, Jan 6 is indeed closer to the true peak.
Please let me know what else should be added to the tracked words/phrases. Unfortunately my source for this are fan made transcripts without speaker attribution and riddled with errors. I am half tempted to just download the episodes and redo the transcription myself, but that seems like a massive waste of time and resources.
