Your words hurt:
How does this work? It uses the YouTube API to search for the top 50 most relevant videos for your search term. For each of those videos, it grabs the latest 50 comments. Then it looks through all that for comments starting with a number followed by a word such as “people,” “youtubers” or “nincompoops.” etc.. Finally, it just replaces the number and the word “people” with “You.”
