I hope platforms like these find a way to attract people outside tech circles. I looked at around a dozen recommended sites and only two of them isn't the personal website of someone who works in tech and writes mostly about tech, which gets boring rather quickly.
There is a world of non-tech bloggers writing stuffs about history, culture and nature who would likely never learn about this project simply because they are not in the right social spaces. I hope there is a way to have them in the ecosystem too.
It doesn't seem very hard to implement in your own site, so it might gain some traction? It's not super-complex, I understand it is some sort of interconnected spin on webrings, which are still somewhat popular among small websites.
If anybody wants to find truly random small websites, I recommend using Wiby (search engine). It has some neat stuff.
