You can filter through the top level comments by keyword; for example you can filter by "remote" to see the massive spike around March 2020. Another interesting thing I found is that I can compare hiring across cities.
I hope you enjoy! I made it so that the links to your search are sharable so if you have some interesting data you should be able to just link the page you're on!
