Comprehensive nesting category system made on PieFeed

Here is the outcome from the brief chat I had here. (Reposted from Fedigrowth)

This is not finished - not in categories, not in organisation, not in community placement, but I'm getting exhausted currently. Many communities on here are old, dead, tired. Some are new. Many categories are barren, some are overfilled and need more segmentation. I'm just sharing what I've built as I think this could be very helpful to community advertisement and exploration.

I'd like anyone who runs or knows of communities to let me know here, so I can add them.

And if anyone is interested, should I make a matrix or even lemmy community in aid of this?
