Thanks for sharing, that's a nice project with a good user experience. That reminds me of the concept of blog "planet" that was somewhat popular in the Linux world a decade ago. Basically an aggregate of blog feeds loosely related to a given topic, you can follow it and have the feeling that you're following a community, without the drama that you have on social media. It's a great concept IMHO, and stupidly simple technically speaking.
Thanks! Yeah. Blog planets are awesome. They defintely played a big role in me coming up with diff.blog. https://rubyland.news/ in particular, which I came across while I was trying to learn Rails. Though diff.blog is built using Django and not Ruby on Rails :)
As an example, Ubuntu still has theirs: https://planet.ubuntu.com/
