Which programming languages have the happiest (and angriest) commenters?

It's officially winter, so what could be better than drinking hot chocolate while querying the new Stack Overflow dataset in BigQuery? It has every Stack Overflow question, answer, comment, and more -- which means endless possibilities of data crunching. Inspired by Felipe Hoffa's post on how response time varies by tag, I wanted to look at the comments table (53 million rows!). To measure happy comments I looked at comments with "thank you", "thanks", "awesome" or ":)" in the body. I limited the analysis to tags with more than 500,000 comments.
