I've been toying with the idea of using that "instances" link at the bottom of this page and exploring each non-blocked instance one at a time and report my findings. When I was a kid before the age of the internet monoliths which exist today I would constantly follow links from one website to another and really enjoyed the process of discovery. I wonder if anyone has already done any Instance delving.

Not really, but I just now was looking at https://lemmyverse.net/ and thinking Beehaw needs to add some banners to the communities. Maybe having regular contests for creators?
