I use the Reddit API to extract the most recent 100 comments from a user. I take those comments and extract sentences that aren't too long and aren't too short. Each sentence is then analyzed using the NLTK Sentiment AnalyzerVader Module and scored based on how positive, negative, and neutral it is. I then rank the analyzed users in order from most positive to least positive.
