      Sentiment analysis is basic data mining.

      Get access to an API and scan the tweets / posts / whatever and look for key words. Hate, dumb, wtf, love, awesome, etc. You can get 60-80% accuracy just counting the number of words that express a sentiment. Literally that simple, just count positive and negative words/phrases. Across a large dataset you can get a decent idea what people think, and there are easy ways to dig deeper.

      And that was the half-assed quick approach, folks who know Markov chains and LLMs could do far, far deeper analysis.
