A couple years ago I found through HN a small webpage that was dedicated to showing hype cycle graphs and usage graphs of different technologies.
For example, you could go to "web development" and it would show a hype graph for a new technology (e.g., polygon), and on another of say, web browser, you could see a graph showing Vivaldi as an emerging technology and Internet Explorer as superseded.
I haven't been able to ever find that site again! Hopefully some of you know it?
