I built this site in response to various ask HN posts asking for niche blogs. I know it's [0] getting hard to find stuff you want in the search results or on big platforms.
It is made with next, newcss, and mdx. It should be easily self hostable with few changes so you can have your own curation site.
Edit: I am aware of the firefox issue now. I fucked up and didn't test on it. And it's fixed now.
